Grammar Rule in 30 Seconds

Use {から|から} to mark a starting point in time/space or to explain a reason.

  • Use for physical starting points: {東京|とうきょう}から {来|き}ました (I came from Tokyo).
  • Use for time: 9{時|じ}から {始|はじ}まります (It starts from 9 o'clock).
  • Use for reasons: {雨|あめ}が {降|ふ}るから {行|い}きません (Because it's raining, I won't go).
Point/Reason + から + Action/Result

Overview

から (kara) is a foundational Japanese particle serving multiple critical functions. While often introduced as meaning both from and because, these seemingly disparate uses converge on a single core linguistic principle: から consistently marks a starting point. This origin can manifest spatially, temporally, as a source (of items or information), or as the logical premise for a reason or cause.
Grasping this unifying concept is essential for mastering から and appreciating its versatility in Japanese.
At the A2 level, you will primarily encounter から in straightforward contexts denoting origin or providing simple reasons. However, understanding its underlying function as a marker of a *point of initiation* allows for a more intuitive and flexible application across various sentence structures. This particle's role extends beyond mere translation, shaping the nuance of communication by establishing clear connections and causality.

How This Grammar Works

から functions as a postposition, meaning it always follows the word or phrase it modifies, attaching directly without intervening particles. Its fundamental role is to delineate the beginning of something, whether physical, temporal, or conceptual. This central idea manifests in two primary grammatical applications: marking an origin or starting point and indicating a reason or cause.
When から designates an origin, it acts similarly to the English from or since, establishing where something commences or emanates. This could be the starting point of a journey, a period in time, or the source from which an item or piece of information was received. For instance, in 日本(にほん)から()ました (Nihon kara kimashita)
I came from Japan
から identifies Japan as the spatial origin of your arrival.
Conversely, when から conveys a reason or cause, it functions akin to because, so, or therefore. Here, the preceding statement establishes the logical starting point or premise that leads to the subsequent conclusion or action. Consider (あめ)()っているから、(かさ)必要(ひつよう)です (Ame ga futteiru kara, kasa ga hitsuyō desu)—"Because it's raining, an umbrella is necessary." The rainfall serves as the causal starting point for the need for an umbrella. In both applications, から precisely pinpoints an initial locus, anchoring the statement to a specific origin.

Formation Pattern

1
The formation of から is direct, primarily attaching to nouns and the plain forms of verbs and adjectives. The precise conjugation depends on the part of speech it follows and whether it's marking an origin or a reason. Keep in mind that から itself does not conjugate.
2
1. Attaching to Nouns:
3
For Origin/Starting Point: Simply append から directly to the noun.
4
| Type | Pattern | Example Japanese | Example English |
5
| :------ | :------------ | :------------------------------------ | :------------------------------------ |
6
| Noun | Noun + から | 東京(とうきょう)から (Tōkyō kara) | from Tokyo |
7
| | | 月曜日(げつようび)から (Getsuyōbi kara) | from Monday / since Monday |
8
| | | 先生(せんせい)から (Sensei kara) | from the teacher (source) |
9
For Reason/Cause: The copula (plain) or です (polite) is mandatory before から when expressing a reason with a noun. Omitting it is a common error.
10
| Type | Pattern | Example Japanese | Example English |
11
| :-------- | :---------------- | :----------------------------------------------- | :---------------------------------------- |
12
| Noun | Noun + だから | 日本人(にほんじん)だから (Nihonjin dakara) | because I'm Japanese |
13
| | | 学生(がくせい)だから (Gakusei dakara) | because I'm a student |
14
| Noun | Noun + ですから | 日本人(にほんじん)ですから (Nihonjin desu kara) | because I'm Japanese (polite) |
15
| | | 学生(がくせい)ですから (Gakusei desu kara) | because I'm a student (polite) |
16
2. Attaching to Verbs (for Cause):
17
から always follows the plain form (dictionary V-る, negative V-ない, past V-た, negative past V-なかった) of a verb when expressing a reason. While V-ますから exists, it's generally more common to use the plain form + から and then make the rest of the sentence polite.
18
| Type | Pattern | Example Japanese | Example English |
19
| :------ | :---------------- | :----------------------------------------------- | :---------------------------------------- |
20
| Verb | V-る + から | ()くから (Iku kara) | because I'm going / will go |
21
| | V-ない + から | ()かないから (Ikanai kara) | because I'm not going / won't go |
22
| | V-た + から | ()ったから (Itta kara) | because I went |
23
| | V-なかった + から | ()かなかったから (Ikanakatta kara) | because I didn't go |
24
| Verb | V-ますから | ()きますから (Ikimasu kara) | because I will go (polite, less common) |
25
3. Attaching to Adjectives (for Cause):
26
から follows the plain form of adjectives for reasons.
27
い-Adjectives: Simply append から to the plain form (or truncated form for past/negative).
28
| Type | Pattern | Example Japanese | Example English |
29
| :-------- | :---------------- | :----------------------------------------------- | :---------------------------------------- |
30
| い-Adj | い-Adj + から | (たか)いから (Takai kara) | because it's expensive |
31
| | | (さむ)くないから (Samukunai kara) | because it's not cold |
32
| | | (あつ)かったから (Atsukatta kara) | because it was hot |
33
な-Adjectives: Similar to nouns, the copula (plain) or です (polite) is essential for -adjectives when stating a reason. Omitting it is a significant error.
34
| Type | Pattern | Example Japanese | Example English |
35
| :-------- | :---------------- | :----------------------------------------------- | :---------------------------------------- |
36
| な-Adj | な-Adj + だから | (しず)かだから (Shizuka dakara) | because it's quiet |
37
| | | (ひま)だから (Hima dakara) | because I'm free / have free time |
38
| な-Adj | な-Adj + ですから | (しず)かですから (Shizuka desu kara) | because it's quiet (polite) |
39
| | | (ひま)ですから (Hima desu kara) | because I'm free / have free time (polite)|
40
It is crucial to differentiate between the plain forms followed by から (e.g., (あめ)()っているから) and polite forms like (あめ)()っていますから. While both are grammatically correct, using the plain form + から followed by a polite sentence ending (e.g., (かさ)必要(ひつよう)です) is generally more common and natural in modern conversation. The です/ますから construction for the reason clause itself can sometimes sound overly formal or slightly stiff.

When To Use It

から is remarkably versatile due to its fundamental role as a marker of a starting point. This guiding principle dictates its usage across various contexts.
1. Marking Origin or Starting Point: This is the most concrete application, specifying the source or commencement of something. The scope ranges from physical locations to abstract concepts.
  • Geographical/Physical Origin: To state where a person, object, or concept originates. For example, (わたし)日本(にほん)から()ました (Watashi wa Nihon kara kimashita)
    I came from Japan.
    This is a standard introductory phrase when stating your nationality or recent travel. Similarly, (えき)から(ある)いて五分(ごふん)です (Eki kara aruite gofun desu) – "It's a five-minute walk from the station," establishing a spatial starting point for a duration.
  • Temporal Starting Point: To specify when something begins or has been in effect since. 会議(かいぎ)三時(さんじ)からです (Kaigi wa sanji kara desu) – "The meeting is from 3 o'clock.
    Or, 昨日(きのう)から(あたま)(いた)いです (Kinō kara atama ga itai desu)
    My head has been hurting since yesterday." Here, 昨日 is the temporal origin of the pain, indicating continuous state.
  • Source of Information/Items: To indicate the provider or grantor of something. 先生(せんせい)から宿題(しゅくだい)をもらいました (Sensei kara shukudai o moraimashita)
    I received homework from the teacher.
    先生 is the source from whom the homework was obtained. You could also receive an email: 会社(かいしゃ)からメールが(とど)いた (Kaisha kara mēru ga todoita)
    An email arrived from the company.
  • Component/Material Origin: To describe what an object is made from. (こめ)から(つく)られたお(さけ) (Kome kara tsukurareta osake)
    Sake made from rice.
    The rice is the foundational material, the origin of the product. This highlights the primary ingredient or raw material.
  • Sequence or Order: To denote the beginning of a process, a list, or an instruction. 最初(さいしょ)から()んでください (Saisho kara yonde kudasai)
    Please read from the beginning.
    This から establishes the starting point for the requested action, implying a sequence.
2. Stating Reason or Cause: This use of から provides a direct explanation or justification for an action, situation, or conclusion. The preceding clause is presented as the logical genesis of the subsequent event.
  • Direct, Assertive Reasons: から is commonly employed when you intend to state a reason clearly and directly. It often implies a straightforward, almost self-evident connection between cause and effect. (いそが)しいから、手伝(てつだ)えません (Isogashii kara, tetsudaemasen) – "Because I'm busy, I can't help." This presents a clear, unambiguous reason for inability. In casual speech, this directness is very natural.
  • Justifying Requests or Commands: Providing a reason with から before a request or command can soften it by offering context, making the directive seem less arbitrary. (つか)れたから、(やす)みたい (Tsukareta kara, yasumitai) – "Because I'm tired, I want to rest.
    Or, in a more urgent context: 時間(じかん)がないから、(いそ)いでください (Jikan ga nai kara, isoide kudasai)
    Because there's no time, please hurry." Here, the reason (lack of time) acts as a logical precedent for the command, explaining its necessity.
  • In Casual Conversation: Among friends and family, から is the most common and natural way to convey reasons. Its directness is often preferred in informal exchanges. 明日(あした)テストがあるから、勉強(べんきょう)しなきゃ (Ashita tesuto ga aru kara, benkyō shinakya)
    Because I have a test tomorrow, I have to study.
    The から here makes the necessity to study a direct consequence of the test.
  • As a Sentence Connector (だから/それだから): When positioned at the beginning of a sentence, だから (dakara) or それだから (soredakara) functions as a strong causal connector, meaning Therefore, "That's why, or So.
    These forms explicitly link a current statement to a previous one as a consequence. For example:
    A. (あめ)()っている。 (Ame ga futteiru.) B. だから()かない。 (Dakara, ikanai.)« – »A. It's raining. B. That's why, I'm not going." This だから` strongly reinforces the logical conclusion based on the preceding statement.

When Not To Use It

Despite its broad utility, から is not universally applicable. Certain contexts demand alternative particles or grammatical structures for correctness or naturalness. Misusing から can lead to awkward or incorrect Japanese.
  • For Destination or Goal: You must never use から to indicate where you are going. For destinations, へ (e) or に (ni) are the correct particles. For example, to state "I'm going to Tokyo,
    you would say 東京(とうきょう)()きます (Tōkyō e ikimasu) or 東京(とうきょう)()きます (Tōkyō ni ikimasu). Using 東京から行きます would incorrectly imply
    I'm going *from* Tokyo." The distinction is about origin versus destination.
  • For Means or Instrument: If you intend to express by means of or using something, the particle で (de) is required. For instance,
    I go by car
    is (くるま)()きます (Kuruma de ikimasu), not 車から行きます. The latter would imply the car is the origin, not the method of travel. This error often arises from directly translating English prepositions.
  • For Passive Agents in Direct Constructions: While から can denote the source from which an item or information was received, for the agent of a direct passive action (the person or thing *causing* a passive event), に (ni) is typically used. For example,
    I was praised *by* the teacher
    is 先生(せんせい)()められました (Sensei ni homeraremashita). Using 先生から褒められました might suggest receiving praise *from* the teacher in a general sense, but specifically marks the direct actor of the passive verb. The choice hinges on whether you emphasize the general source or the direct perpetrator of the action.
  • For Very Polite, Indirect, or Objective Explanations (Prefer ので): While ~です / ~ますから can convey politeness, から for reasons tends to be more direct and can sometimes sound assertive, blunt, or even like an excuse in formal contexts. In situations demanding utmost politeness, indirectness, or an objective explanation seeking understanding rather than stating a definitive cause, ので (node) is generally preferred. For example, when apologizing for an absence, (ねつ)があるからです (Netsu ga aru kara desu) (
    Because I have a fever
    ) is factual, but (ねつ)がありますので (Netsu ga arimasu node) is softer and more deferential. The ので form implicitly seeks the listener's understanding or permission, making it ideal for apologies, requests, or explaining unfortunate circumstances without sounding confrontational. This nuance is crucial for appropriate social communication in Japanese.
  • When Indicating Sequential Actions (after doing X): から by itself does not mean after doing X. For sequential actions, you must use the て-form of the verb followed by から, forming V-てから (V-te kara). For example, After eating is ()べてから (tabete kara), not 食べるから or 食べたから. The V-てから structure emphasizes the completion of the first action before the second commences, often implying a logical next step or dependency. Confusing this is a major grammatical error.

Common Mistakes

Learners frequently encounter specific pitfalls when employing から. Awareness of these common errors and understanding their underlying causes will significantly aid in avoiding them and achieving more natural Japanese.
  • Omitting with -adjectives and Nouns for Reasons: This is a very pervasive error. You must include the plain copula (or polite です) when using -adjectives or nouns to state a reason before から. For instance, きれいから (kirei kara) is incorrect; the correct forms are きれいから (kirei da kara) or きれいですから (kirei desu kara). Similarly, 学生(がくせい)から (gakusei kara) meaning "because I'm a student" is wrong; it must be 学生(がくせい)から (gakusei da kara). This mistake often stems from learners incorrectly applying the pattern of い-adjectives (which directly attach から) to nouns and -adjectives.
  • Incorrect Word Order: から is a postposition and must always directly follow the word or phrase it modifies. A common mistake, influenced by English syntax, is placing it before the noun or verb. For example, instead of the incorrect から日本(にほん)()ました (kara Nihon kimashita), the correct form is 日本(にほん)から()ました (Nihon kara kimashita)came from Japan. Always remember that particles in Japanese specify the function of the word *before* them.
  • Confusing から (Reason) with ~てから (After Doing): This is a critical point of confusion that fundamentally alters meaning. While から alone indicates a reason, V-てから (te-form + から) is a distinct grammatical construction meaning after doing X. For example, ご飯(はん)()べたから、(ねむ)い (Gohan o tabeta kara, nemui) means "Because I ate, I'm sleepy.
    However, ご飯(はん)()べてから、()ます (Gohan o tabete kara, nemasu) means
    After eating, I will sleep." The presence of the て-form explicitly marks sequential actions, not causality. Ignoring this distinction leads to significant miscommunication.
  • Overuse of です / ますから in Casual Settings: While grammatically permissible, using です / ます directly before から to express a polite reason can sound stiff or overly formal in casual conversations. In such contexts, simply using the plain form of the verb/adjective/noun + から is more natural, even if the rest of the sentence ends politely. For instance, a casual way to say "Because it's hot, let's open the window" would be (あつ)いから、(まど)()けよう (Atsui kara, mado o akeyō), rather than (あつ)いですから、(まど)()けましょう. This is a matter of register and conversational flow; choosing the appropriate level of formality is key to sounding natural.
  • Using から Instead of for Direct Passive Agents: As previously discussed, when specifying *who* performed an action to you in a passive sentence, is generally preferred over から because precisely marks the agent. For example,
    I was bitten by a dog
    is (いぬ)()まれました (Inu ni kamaremashita), not 犬から噛まれました. The から form might vaguely imply the dog as a source, rather than the direct perpetrator, which is typically not the intended nuance. clarifies the direct agent, which is crucial in such constructions.

Common Collocations

から frequently appears in set phrases and common expressions, many of which are essential for natural and idiomatic Japanese communication. These collocations demonstrate から's versatility as a marker of origin, duration, or reason.
  • ~から()ました (~ kara kimashita): I came from ~ or It came from ~. This is a fundamental phrase for introducing your origin. Example: (わたし)はアメリカから()ました (Watashi wa Amerika kara kimashita)
    I came from America.
    This is a standard self-introduction.
  • ~から(はじ)まります (~ kara hajimarimasu): It starts from ~. Used for events, processes, or periods. Example: 授業(じゅぎょう)九時(くじ)から(はじ)まります (Jugyō wa kuji kara hajimarimasu) – "Classes start from 9 o'clock." This specifies a temporal beginning.
  • ~から(えら)んでください (~ kara erande kudasai): Please choose from ~. Implies selection from a group or list. Example: このメニューから(えら)んでください (Kono menyū kara erande kudasai)
    Please choose from this menu.
    Here, から marks the set of options as the source of selection.
  • だから (dakara): Therefore, "That's why,« »So.
    A powerful causal connector often used at the beginning of a sentence to link it to a previous statement. Example: 今日(きょう)(あめ)です。だから、洗濯(せんたく)しません。 (Kyō wa ame desu. Dakara, sentaku shimasen.)
    It's raining today. Therefore, I won't do laundry." This is very common in spoken Japanese, providing a direct consequence.
  • それだから (soredakara): Similar to だから, but often carrying a stronger emphasis, meaning "That's precisely why or Exactly for that reason.
    It can imply a more definitive or even slightly exasperated tone. Example: A: 時間(じかん)がないでしょう? (Jikan ga nai deshō?) B: それだから(いそ)ぐんです。 (Soredakara, isogunda.)
    – "A: You don't have time, right? B: That's precisely why, I'm hurrying." This それだから` adds a layer of conviction or justification.
  • 今日から (kyō kara): Starting from today. A common temporal marker. Example: 今日(きょう)からダイエットを(はじ)めます (Kyō kara daietto o hajimemasu) – "I'm starting a diet from today." This clearly marks the initiation of an ongoing action.
  • ~からもらいました (~ kara moraimashita):
    I received it from ~.
    Used to indicate the source of something given. Example: 友達(ともだち)からプレゼントをもらいました (Tomodachi kara purezento o moraimashita)
    I received a present from my friend.
    The friend is the giver, the source of the gift.
  • なぜなら~から (nazenara ~ kara):
    The reason is because ~.
    A more formal and emphatic way to introduce a reason, often used when explaining something formally or making a strong justification. なぜなら sets up the explanation, and から completes it. Example: (かれ)会議(かいぎ)(おく)れました。なぜなら、電車(でんしゃ)(おく)れたからです。 (Kare wa kaigi ni okuremashita. Nazenara, densha ga okureta kara desu.)
    He was late for the meeting. The reason is because the train was delayed.
    This is a robust construction for providing detailed and often weighty reasons.
  • ~から~まで (~ kara ~ made): From ~ to ~. This particle pair is essential for expressing duration, range, or extent. Example: 月曜日(げつようび)から金曜日(きんようび)まで(はたら)きます (Getsuyōbi kara Kinyōbi made hatarakimasu)
    I work from Monday to Friday.
    Here, 月曜日 is the explicit start, and 金曜日 is the explicit end, defining the entire span.

Contrast With Similar Patterns

Understanding から often necessitates differentiating it from other particles or grammatical structures that may appear similar but carry distinct meanings or nuances. Mastering these distinctions is crucial for precise and appropriate communication in Japanese.
1. から vs. まで (made)
These two particles are frequently learned in tandem as they form a natural pair, marking the beginning and end of a range or duration. They are often used together to delineate a complete span.
| Feature | から (kara) | まで (made) |
| :--------- | :----------------------------------------------- | :------------------------------------------------ |
| Meaning| From, since, starting point | Until, to, up to, endpoint |
| Function| Marks the origin (spatial, temporal, logical) | Marks the extent or conclusion (spatial, temporal)|
| Example| 東京(とうきょう)から (Tōkyō kara) | 大阪(おおさか)まで (Ōsaka made) |
| | (あさ)から (Asa kara) | (よる)まで (Yoru made) |
| Pairing| Often used in tandem: Noun1から Noun2まで | Often used in tandem: Noun1から Noun2まで |
An illustrative example of their pairing: 大阪(おおさか)から東京(とうきょう)まで、新幹線(しんかんせん)()きます (Ōsaka kara Tōkyō made, shinkansen de ikimasu)
I will go from Osaka to Tokyo by Shinkansen.
The から defines the departure point, and まで defines the arrival point, clearly mapping the extent of the journey.
2. から vs. より (yori)
While both から and より can convey a sense of from or origin, their primary modern uses are distinct. Understanding this historical shift is key to avoiding anachronisms or misinterpretations.
| Feature | から (kara) | より (yori) |
| :--------- | :----------------------------------------------- | :------------------------------------------------ |
| Meaning| From, since, because, starting point | Than (for comparison), from (literary/archaic origin)|
| Function| Everyday origin, causal explanation | Comparative marker, formal/literary origin |
| Example| 日本(にほん)から()ました (Nihon kara kimashita) | (わたし)(かれ)より()(たか) (Watashi wa kare yori se ga takai)|
| | 三時(さんじ)から (Sanji kara) | 東京(とうきょう)より大阪(おおさか)() (Tōkyō yori Ōsaka ga suki)|
Historically, より had a broader meaning encompassing from. However, in contemporary Japanese, its overwhelming primary function is as a comparative particle meaning than. If you wish to indicate an everyday origin (spatial, temporal, or source), から is always the correct and natural choice. For instance, when inquiring about someone's place of origin, you would ask どこから()ましたか (Doko kara kimashita ka), never どこより来ましたか. The usage of より for origin is largely confined to highly formal contexts, literature, or older expressions, making から the default for A2 learners.
3. から vs. ので (node) (Both meaning because)
This distinction is arguably the most critical for A2 learners grappling with expressing reasons, as both から and ので translate as because or so. However, they carry significantly different nuances regarding politeness, directness, and implied consequence, reflecting important aspects of Japanese social communication.
| Feature | から (kara) | ので (node) |
| :------------ | :------------------------------------------------ | :------------------------------------------------ |
| Core Idea | Direct reason, assertive conclusion. States a reason for action/situation. | Objective reason, softer explanation. Presents contextual information. |
| Grammar | Plain form + から. N/な-Adj + だから. (です/ますから possible but specific.) | Plain form + ので. N/な-Adj + なので. (です/ますので common, highly polite.) |
| Tone | Direct, assertive, sometimes implies personal judgment or opinion. Can be blunt. | Objective, explanatory, softer, seeks understanding or expresses deference. |
| Politeness| Can be casual or formal, but often more direct in explaining the cause. | Generally more polite, indirect, and less confrontational. Preferred in formal settings, requests, or apologies. |
| Use Case | Strong statements, commands, personal reasons, casual speech, offering a justification. | Apologies, requests, formal reports, when needing to sound gentle or when the consequence is not fully determined. Often used when the reason *is* the consequence. |
Consider these comparative examples to highlight the nuance:
  • (つか)れたから、もう(かえ)ります (Tsukareta kara, mō kaerimasu).
"Because I'm tired, I'm going home now." (This is a direct, personal reason, sounding like a firm decision. In some contexts, it can come across as assertive or an excuse, stating the cause as an undeniable fact.)
  • (つか)れましたので、もう(かえ)ります (Tsukaremashita node, mō kaerimasu).
"Since I'm tired, I'm going home now." (This is a softer, more polite explanation. It presents tiredness as an objective circumstance, implying the listener might understand or implicitly grant permission. This is generally more appropriate in situations requiring deference, such as excusing yourself from work or making a request to leave.)
The choice between から and ので reflects a significant aspect of Japanese communication: the preference for indirectness and consideration for the listener in formal or sensitive situations. While から states a fact or a direct justification, ので presents it as contextual information, allowing the listener more room to respond without feeling directly challenged. Always opt for ので when you need to be especially polite, when making a request that might inconvenience someone, or when an apology is involved, as it creates a softer, more accommodating impression.

Quick FAQ

Q: Can から follow a noun and a verb in the same sentence?
A: Yes, this is very natural and common, especially when から serves different functions. Each instance of から fulfills its specific grammatical role independently within the sentence. For instance, 日本(にほん)から()たから、日本食(にほんしょく)()きです (Nihon kara kita kara, Nihonshoku ga suki desu) means
Because I came from Japan, I like Japanese food.
The first から marks origin (日本から), and the second marks the reason (来たから).
Japanese grammar allows for such functional layering.
Q: Is だから the same as だ + から?
A: Yes, だから functions as a single conjunctive expression, though it is indeed a contraction of だ + から. It means Therefore, "That's why, or So," and is commonly used to begin a sentence, linking it causally to a previous statement. For example, `(あめ)()っている。だから、(そと)()ない。
(Ame ga futteiru. Dakara, soto ni denai.) – "It's raining. So, I won't go outside." While technically derived from the copula and から`, it's best understood as a standalone causal connector when initiating a new sentence, emphasizing the direct consequence of the preceding information.
Q: When does から mean after instead of from or because?
A: から means after doing X specifically when it is attached to the て-form of a verb, forming the distinct grammatical construction V-てから (V-te kara). For example, ()べてから (tabete kara) means after eating. This structure emphasizes the completion of the first action before the subsequent action begins, indicating a temporal sequence. This てから construction should not be confused with V-るから or V-たから, which solely indicate reasons.
Q: Can I use から to start a sentence?
A: Yes, you can, especially when using だから or それだから, which are common sentence-initial causal connectors as explained in the Common Collocations section. These forms explicitly connect the new sentence to a preceding statement, providing a cause or consequence. Using から directly after a plain form (e.g., `寒いから。
(Samui kara.)) at the very beginning of a new sentence is also possible in very casual speech, often implying a follow-up action or thought that is left unsaid but understood within context. However, for clear, grammatically complete sentences, だから` is the more standard and universally understood choice to open a causal statement.

💡

一个助词,三个身份

から 可以标记空间的起点(从东京)、时间的起点(从周一)和逻辑的起点(因为)。核心逻辑都是“出发点”。记住这一点,你就不会混淆了。比如:«{東京|とうきょう}から{来|き}ました。»
⚠️

语序绝对不能乱

から 必须紧跟在它修饰的词后面,绝对不能放在前面。«{東京|とうきょう}から» 是对的,但 «から{東京|とうきょう}» 是错的。这和英语或中文的“从”刚好相反。比如:«{九時|くじ}から{始|はじ}まる。»
🎯

语气要统一

在非正式聊天中用“普通形 + から”,在正式场合用“礼貌形 + から”。混用会很别扭,比如 «{眠|ねむ}いですから{帰|かえ}る» 就有点怪。建议统一成:«{眠|ねむ}いから{帰|かえ}る。»
💬

“所以我才说嘛!”

在日常口语中,单独说一句 «だから!» 意思是“我早就说过了吧!”或者“就是说啊!”。这是一种表达强调或小小无奈的常用感叹词。比如:«だから、{言|い}ったじゃない!»

Smart Tips

If you want to sound more polite, swap 'kara' for 'node'.

{忙|いそが}しいから、{行|い}けません。 {忙|いそが}しいので、{行|い}けません。

Use 'kara' to set a clear start time.

9{時}に{始|はじ}まります。 9{時|じ}から{始|はじ}まります。

Always add 'da' to nouns before 'kara'.

{雨|あめ}から、{行|い}かない。 {雨|あめ}だから、{行|い}かない。

Use 'kara' and 'made' together for clarity.

{東京|とうきょう}から{行|い}きます。 {東京|とうきょう}から大阪まで{行|い}きます。

发音

ka-RA

Pitch Accent

The particle 'kara' usually has a low-high pitch.

Question

记住它

记忆技巧

Think of 'Kara' as a 'Car' starting its engine. It's the starting point of your journey!

视觉联想

Imagine a starting line at a race track with the word 'KARA' written in big, bold letters. Every time you see 'KARA', visualize a car zooming away from that line.

Rhyme

From the start, use Kara, it's the best by far.

Story

Kenji stood at the station. He looked at his watch. '9 o'clock from here,' he said. Because he was early, he bought a coffee. He used 'kara' for the time and the reason.

Word Web

{東京|とうきょう}から{明日|あした}から{好|す}きだから{雨|あめ}だから{来|き}ました{始|はじ}まる

挑战

Write 3 sentences about your day using 'kara' (e.g., 'I woke up from 7', 'I am tired because I worked').

文化笔记

Used universally in all regions.

Sometimes 'kara' is replaced by 'kara' or 'yori' in specific contexts.

In business, 'kara' is often replaced by 'node' to sound more polite.

Derived from the verb {枯れる|かれる} (to wither/end), marking the 'end' of a state which becomes the 'start' of another.

常见问题 (8)

It is very versatile, but use 'node' for formal reasons.

Because 'kara' attaches to clauses, and nouns need 'da' to act like a clause.

It is 'from' for space/time and 'because' for reasons.

Yes, it can imply a reason without stating the result.

It is neutral. Use 'node' for formal.

Yes, just attach it to the dictionary form.

'Kara' is the start, 'made' is the end.

It will sound like a beginner mistake.
