Connecting Japanese Adjectives: and/because (~くて)
い-adjectives by replacing the final い with くて to sound more natural and descriptive.
Grammar Rule in 30 Seconds
To connect two i-adjectives, drop the final 'i' and add 'kute'.
- Drop final 'i' from i-adjective: {暑い|あつい} → {暑く|あつく} + te = {暑くて|あつくて}
- Use for listing attributes: {この|この} {本|ほん}は {面白くて|おもしろくて} {安い|やすい} (This book is interesting and cheap).
- Use for reasons: {お腹|おなか}が {空いて|すいて} {苦しくて|くるしくて} {死にそう|しにそう} (I'm hungry and it's painful/I'm dying).
Overview
Japanese grammar often connects clauses and ideas using non-finite forms, deferring the final tense and politeness to the sentence’s conclusion. The ~くて (-kute) form of い-adjectives (形容詞 {けいようし}) is a prime example of this principle, allowing you to link descriptive elements seamlessly. At the A2 level, mastering ~くて significantly expands your ability to construct more complex and natural Japanese sentences.
It serves two primary functions: first, to connect multiple い-adjectives that describe a single subject, analogous to "and" in English; and second, to express a reason or cause, functioning similarly to "because" or "and so." This grammatical structure enables you to move beyond simple, isolated statements and articulate nuanced relationships between ideas without redundancy. Fundamentally, ~くて is a conjunctive form that transforms an い-adjective into a connective element, allowing it to modify a subsequent clause without fully concluding the previous one. This means ~くて itself carries no inherent tense or politeness; these are determined entirely by the final predicate (verb or adjective) of the sentence.
Understanding this inherent neutrality is key to its flexible and widespread use in Japanese communication.
How This Grammar Works
~くて, you are observing an い-adjective in its conjunctive form, serving as a bridge between clauses. This bridge can convey one of two main logical relationships: sequential description or causation. Both stem from the い-adjective preceding the ~くて providing context or a premise for the following statement.い-Adjectives: Listing Attributes~くて connects two or more い-adjectives, it indicates that the qualities described by these adjectives coexist or are simultaneously true for the subject. This usage effectively functions as "and," allowing you to chain descriptions without repeating the predicate.小さくて可愛い (ちいさくて かわいい). The non-finite nature of 小さくて ensures the description flows into 可愛い to form a single, cohesive thought. You'll use this when you want to paint a more complete picture of an object or situation.この本は古くて、面白いです。
今日は暖かくて、気持がいいですね。
~くて is to indicate that the state described by the initial い-adjective is the reason or cause for the event or situation in the subsequent clause. This implies "because (it is/was) X, (therefore) Y." The causal link is often clear from context, but ~くて efficiently establishes this relationship. For example, 寒くて、外に出たくありません (さむくて, そとにでたくありません) means "Because it's cold, I don't want to go outside." Here, the coldness (寒い) directly explains the desire to stay indoors.忙しくて、宿題ができませんでした。
嬉しくて、涙が出ました。
~くて is itself tense-neutral and politeness-neutral. The tense (past, present) and politeness level (casual, polite) of the entire sentence are exclusively determined by the final predicate. If the sentence concludes with a plain form, the entire statement is casual; if it ends with ~です (-desu) or ~ます (-masu), it becomes polite.Formation Pattern
~くて form for い-adjectives is a systematic process, applying to nearly all adjectives that end in い. This conjugation creates a non-finite form, allowing the adjective to connect to other words or clauses.
い-Adjectives:
い-adjective into its ~くて form, you follow a simple two-step process:
い-adjective (e.g., 高い {たかい}).
い ({い}) from the adjective.
い with くて ({くて}).
~くて Form | ~くて Form Reading |
高|たかい | high/expensive | 高|たか | 高くて|たかくて | takakute |
早|はやい | fast/early | 早|はや | 早くて|はやくて | hayakute |
小|ちいさい | small | 小|ちいさ | 小|ちいさくて | chiisakute |
美味|おいしい | delicious | 美味|おいし | 美味|おいしくて | oishikute |
忙|いそがしい | busy | 忙|いそがし | 忙|いそがしくて | isogashikute |
いい ({いい}) / よい ({よい}) Exception:
いい ({いい}), meaning "good." While いい is its common dictionary form, all its formal conjugations derive from its classical root, よい ({よい}). Therefore, its ~くて form is always よくて ({よくて}), not いいくて. This irregularity extends to compound い-adjectives that incorporate いい, such as かっこいい ({かっこいい}, cool/handsome), which becomes かっこよくて ({かっこよくて}).
今日は天気が良くて、最高ですね。
格好良くて素敵な人。
い-Adjectives (~くない {~くない}):
~くて form of a negative い-adjective, you must first create the negative form, which ends in ~くない ({~くない}). Since ~くない itself functions grammatically as an い-adjective, you apply the same ~くて rule to it:
い-adjective (e.g., 高い {たかい}).
い and add くない ({くない}) (e.g., 高くない {たかくない}).
~くない as a new い-adjective: remove the final い ({い}) from ~くない (e.g., 高くな {たかくな}).
くて ({くて}) to the remaining stem (e.g., 高くなくて {たかくなくて}).
~くて Form | English Translation |
高|たかい | 高|たかくない | 高|たかくなくて | not high/expensive and... |
早|はやい | 早|はやくくない | 早|はやくなくて | not fast/early and... |
美味|おいしい | 美味|おいしくない | 美味|おいしくなくて | not delicious and... |
あのレストランは美味しくなくて、高いです。
When To Use It
~くて form provides a flexible way to combine descriptive elements and express logical relationships. Its effective use depends on understanding the context and the precise nuance you wish to convey.~くて when you want to describe an object, person, or situation with multiple い-adjectives that are true at the same time. The order of adjectives usually doesn't imply a strong emphasis unless one is clearly more significant in context.彼は優しくて、面白いです。
このカメラは軽くて、小、使いやすいです。
い-adjective directly leads to or explains the following clause, ~くて takes on a causal meaning. This is similar to using "because" or "so" in English. The nuance here is that the first clause is the reason for the second.頭が痛くて、仕事を休みました。
悲しくて、何も食べられませんでした。
い-Adjective to a Following Verb or な-Adjective Predicate:~くて exclusively forms from い-adjectives, the clause it initiates can be followed by various types of predicates. This includes verbs, な-adjectives, or even other い-adjectives that serve as the main predicate of the sentence. Remember, the final predicate determines the overall tense and politeness.この部屋は広くて、快適です。(Connectingい-adjective広いtoな-adjective快適{かいてき} viaです{です}.)
本が面白くて、徹夜して読んでしまいました。(Connectingい-adjective面白いto a verb phrase徹夜して読んでしまいました.)
- For
な-adjectives:な-adjectives use the~で(-de) form (e.g.,静かで{しずかで}, "quiet and..."). Never substitute~くてfor~でwithな-adjectives. - To imply a conditional "if": Although
~くてcan express a reason, it does not mean "if." For conditional statements with adjectives,~たら(-tara),~ば(-ba), or~と(-to) are used with different structures. For example,高かったら買わない(たかかったら かわない) means "If it's expensive, I won't buy it." - Connecting nouns:
~くてis for adjectives. Nouns useと(-to) orで(-de) for connection, depending on the context.
Common Mistakes
~くて form. Recognizing and actively correcting these will refine your Japanese significantly.~くて with ~と ({~と}) for Adjective Connection:と primarily connects nouns (私と彼 わたしと かれ: "I and he") or expresses a general conditional ("if"/"when") with verbs and adjectives (e.g., 高いと買わない たかいと かわない: "If it's expensive, I won't buy it."). It never functions as a simple "and" between adjectives.- Incorrect:
この料理は安いと美味しいです。(Sounds like: "If this dish is cheap, it's delicious.") - Correct:
この料理は安くて、美味しいです。("This dish is cheap and delicious.")
いい ({いい}) / よい ({よい}):いい to よくて ({よくて}) transformation is perhaps the most frequently overlooked い-adjective conjugation. Using いいくて ({いいくて}) is a clear grammatical error that immediately signals a non-native speaker. Remember that all conjugations of いい stem from its classical root, よい ({よい}).- Incorrect:
天気がいいくて、散歩しました。 - Correct:
天気が良くて、散歩しました。("The weather was good, so I took a walk.")
~くて with な-Adjectives (形容動詞 {けいようどうし}):な-adjectives follow a distinct conjunctive rule, using ~で (-de). Substituting ~くて for ~で with な-adjectives is a common grammatical error. This distinction is fundamental.- Incorrect:
あの人は静かくて、親切です。 - Correct:
あの人は静かで、親切です。("That person is quiet and kind.")
~くて:~くて form. The last adjective or predicate in a sentence determines its overall tense and politeness and must appear in its appropriate ending form (dictionary form, ~です, ~ました, etc.). Using ~くて on the final element makes the sentence grammatically incomplete or awkward.- Incorrect:
この映画は面白くて、感動的でです。(Incorrectly attempting to apply~くてlogic to aな-adjective's end form with a redundantです.) - Correct:
この映画は面白くて、感動的です。("This movie is interesting and moving.")
~くて often results in cumbersome and unnatural-sounding Japanese. Native speakers generally prefer conciseness. As a guideline, limit chains to two or three adjectives for natural expression. For more than three, consider rephrasing or using separate sentences to maintain clarity and flow.- Less Natural:
この鞄は軽くて、安くて、小、使いやすいです。 - More Natural:
この鞄は軽くて使いやすいです。それに、安いです。("This bag is light and easy to use. Furthermore, it's cheap.")

Quick FAQ
~くて form.- Q: Can
~くてbe used with verbs?
~くて is exclusively a conjunctive form for い-adjectives. Verbs use their て-form (~て) for similar connective purposes. Although an い-adjective clause ending in ~くて can precede a verb, the ~くて itself does not conjugate a verb.
- Example (verb
て-form):疲れて、家に帰りました。(つかれて, いえにかえりました.) "I got tired and went home." (疲れてis theて-form of the verb疲れる{つかれる}). - Example (adjective
~くてleading to a verb):忙しくて、食事を忘れてしまいました。(いそがしくて, しょくじをわすれてしまいました.) "Because I was busy, I forgot to eat." (忙しくてis the~くてform of theい-adjective忙しい{いそがしい}).
- Q: What is the maximum number of adjectives I can connect with
~くて?
While grammatically, you could theoretically chain many, for natural and clear Japanese, it is strongly advised to limit your chains to two or three adjectives. Longer chains tend to make sentences unwieldy and difficult for the listener or reader to process. If you have numerous attributes, consider breaking them into multiple sentences or using other connective expressions to maintain clarity and natural flow. Native speakers prioritize conciseness.
- Q: Is
~くてpolite or casual?
The ~くて form itself is entirely neutral regarding politeness. It acts as a connector, passing on the politeness and tense information to the sentence's final predicate. Therefore, the overall politeness of the sentence is determined by how it ends.
- Polite:
今日は暖かくて、気持ちがいいです。(きょうはあたたかくて, きもちがいいです.) (ですmakes it polite.) - Casual:
今日は暖かくて、気持ちがいい。(きょうはあたたかくて, きもちがいい.) (Plain formいいmakes it casual.)
- Q: How do I handle negative
い-adjectives with~くて?
As detailed in the "Formation Pattern" section, negative い-adjectives (~くない {~くない}) function as い-adjectives themselves. Thus, you apply the standard ~くて rule to them: remove the final い from ~くない and attach くて, resulting in ~くなくて ({~くなくて}).
- Example:
美味しくない({おいしくない}, "not delicious") becomes美味しくなくて({おいしくなくて}, "not delicious and/because"). このラーメンは美味しくなくて、期待はずれでした。(このラーメンはおいしくなくて, きたいはずれでした.) "This ramen was not delicious, and it was disappointing."
- Q: Does
~くてalways imply "because"?
No, not exclusively. The interpretation as "because" or "and so" depends heavily on the logical relationship between the two clauses and the context. If the first clause clearly presents a reason or cause for the second, then the causal meaning is intended. If the clauses simply list co-occurring attributes without a strong cause-effect link, then ~くて functions purely as "and." Often, ~くて can subtly imply both a descriptive and a causal link simultaneously, making it a highly versatile connector.
部屋が広くて明るい。(へやがひろくて あかるい.) "The room is spacious and bright." (Listing attributes.)部屋が広くて気持ちがいい。(へやがひろくて きもちがいい.) "The room is spacious, and so it feels good." (Implies the spaciousness is a reason for the good feeling.)
