かりる

The Japanese verb かりる (kariru), written in kanji as 借かりる, is a fundamental Ichidan (Group 2) verb that primarily translates to 'to borrow' or 'to rent' in English. At its core, it describes the act of receiving something from another person or entity with the explicit understanding and intention that it will be returned at a later time. Unlike English, which often distinguishes between 'borrowing' (usually for free from a friend) and 'renting' (paying for use, like an apartment or car), Japanese frequently uses kariru for both scenarios, though more specific terms like rentaru or chinshaku exist for formal contexts.

Core Concept

The temporary transfer of possession from a source to the subject.

In the Japanese social fabric, the act of borrowing is deeply tied to the concept of giri (social obligation). When you borrow something, you are not just taking an object; you are entering into a temporary state of indebtedness. This is why the word is often paired with polite auxiliary verbs like ~te morau (to have the favor of borrowing). The word can also be used metaphorically, such as borrowing someone's wisdom (知恵ちえを借かりる) or borrowing a hand (手てを借かりる) which means to ask for help. Understanding kariru requires recognizing the direction of the action: the object moves toward the speaker or the subject. This is the opposite of kasu (to lend), where the object moves away from the subject.

Grammatical Category

Ichidan Verb (Group 2), Transitive.

Etymologically, kariru evolved from the older form karu. In modern Japanese, karu is still used in some dialects or specific literary contexts, but kariru is the standard form. The kanji 借 consists of the 'person' radical (亻) and the phonetic/semantic component 昔 (old/past), suggesting the idea of something that was previously held by another. When using this verb, the person you borrow from is marked with the particle に (ni) or から (kara), and the object being borrowed is marked with を (o). For example, 'Tanaka-san ni kane o kariru' (Borrow money from Mr. Tanaka). The use of に emphasizes the source as a person, while から can feel more like the point of origin, often used with institutions like banks or libraries.

Polite Usage

拝借する (haishaku suru) is the humble version used in business.

Furthermore, kariru is used in the context of renting property. If you are 'renting' an apartment, you say 'apaato o kariru'. This differs from 'kasu' (to rent out/lease to someone). In the housing market, the person borrowing/renting is the karinushi. This versatility makes it one of the most high-frequency verbs in the Japanese language, appearing in daily conversations, financial transactions, and idiomatic expressions alike. Whether it is a physical object like a pen, a financial asset like a loan, or a metaphorical 'hand' for assistance, kariru encompasses the entire spectrum of temporary acquisition. Its importance in A2 level Japanese cannot be overstated, as it forms the basis for many social interactions and polite requests.

Using かりる (kariru) correctly involves understanding its conjugation as an Ichidan verb and its relationship with particles. Because it is an Ichidan verb, conjugation is straightforward: you simply drop the final -ru and add the desired suffix. For the polite form, it becomes karimasu; for the negative, karinai; for the past, karita; and for the 'te-form', karite. This simplicity makes it an ideal verb for beginners to master early on. However, the complexity lies in the particles used to define the source and the object of the borrowing.

Particle Structure

[Source] に/から [Object] を かりる

When borrowing from a person, に (ni) is the most common particle to indicate the source. It implies a direct, personal connection. から (kara) can also be used, especially when the source is an institution or when you want to emphasize the movement of the object from one point to another. For example, 'Ginkou kara okane o kariru' (Borrow money from the bank) is more common than using 'ni' in that context. The object being borrowed is always marked with を (o). If you want to ask someone if you can borrow something, you would use the ~te mo ii desu ka pattern: 'Kore o karite mo ii desu ka?' (May I borrow this?).

Common Patterns

~te-form + morau (to have someone lend you something).

In more formal or business situations, kariru is replaced by 拝借する (haishaku suru). This is a humble verb (kenjougo) that lowers the speaker's status while raising the lender's status. For instance, 'O-namae o haishaku shite mo yoroshii desu ka?' is a very formal way to ask for someone's name (literally, 'May I borrow your name?'). Another important aspect is the duration. If you are borrowing something for a long time or paying for it, kariru still applies, but you might see it in compound words like karikaeshi (borrowing and returning). In the context of renting a house, you are the shakuyanin (renter), and the act is heya o kariru.

Transitivity

Kariru is transitive, meaning it always acts upon an object (the thing borrowed).

Finally, consider the psychological weight of the verb. In Japan, borrowing money (okane o kariru) is often viewed with more gravity than in some Western cultures. It implies a significant burden of trust. Similarly, 'borrowing a hand' (te o kariru) is a humble way to admit you cannot do something alone. When you use kariru, you are acknowledging your reliance on others, which is a key component of Japanese social harmony. Mastery of this verb involves not just knowing the grammar, but understanding the subtle social contract that comes with every act of borrowing. Whether you are at a rental shop, a library, or with a colleague, kariru is your gateway to cooperative interaction.

The verb かりる (kariru) is ubiquitous in Japanese daily life, echoing through various environments from the sterile halls of a bank to the casual atmosphere of a friend's living room. One of the most common places you will encounter this word is at the library (toshokan). Staff will ask if you have a library card to borrow books: 'Hon o kariru no ni kaado ga hitsuyou desu.' You will also see it on signs in rental shops, such as those for DVDs (though declining), cars (rentakaa), or traditional clothing like Kimonos. In these commercial settings, kariru is the standard way to express the customer's action of renting.

Commercial Context

Rental services often use 'Kashidashi-chu' (Currently lent out/unavailable).

In educational settings, students frequently use kariru. Whether it's borrowing an eraser (keshigomu), a textbook (kyoukasho), or notes from a missed lecture, the word is central to student cooperation. You'll hear phrases like 'Chotto keshigomu karite mo ii?' (Can I borrow your eraser for a second?). In the office or workplace, the word takes on a slightly more professional tone. Colleagues might borrow a stapler or a charging cable. In meetings, you might hear the idiomatic 'Chie o kariru' when a team is stuck and needs external input or a fresh perspective. The word is also vital in real estate; when looking for an apartment, the agent will ask what kind of room you want to 'kariru'.

Social Context

Borrowing an umbrella (kasa) is a very common scenario during the rainy season.

Another frequent context is banking and finance. While 'loan' is roon, the act of taking that loan is kariru. You will hear this in news reports about interest rates or in personal conversations about buying a house (juutaku roon o kariru). In casual social gatherings, if someone is taking a photo, they might say 'Basho o karite mo ii desu ka?' (May I use/borrow this space?). This shows the flexibility of the word—it's not just for physical objects you take away, but also for the temporary use of a space or a position. Even in idiomatic Japanese, the word appears in the famous saying 'Neko no te mo karitai' (I want to borrow even a cat's paw), used when someone is incredibly busy and needs any help they can get, however small.

Public Announcements

Train stations often have 'free borrowing' umbrellas called 'Okaeshi-kasa'.

Finally, in the digital world, you might hear kariru in the context of cloud storage or server space, though kariru is increasingly being supplemented by katakana terms like 'rentaru'. However, the fundamental concept remains the same. Whether you are watching a variety show where a comedian 'borrows' a joke from a veteran, or reading a news article about a country 'borrowing' cultural elements from another, kariru is the linguistic thread that connects these acts of temporary acquisition. Its prevalence makes it a 'must-know' for anyone navigating Japanese society, as it appears in almost every facet of interaction where resources are shared or exchanged.

The most frequent and significant mistake learners make with かりる (kariru) is confusing it with its counterpart, かす (kasu). In English, the words 'borrow' and 'lend' are distinct, but learners often mix them up because they both involve the same transaction. Remember: Kariru is 'to borrow' (I get it from you), while Kasu is 'to lend' (I give it to you). If you say 'Pen o kashite kudasai', you are asking someone to lend you a pen. If you say 'Pen o karite mo ii desu ka?', you are asking if you may borrow the pen. The result is the same, but the subject of the verb changes.

The Kariru vs. Kasu Trap

Kariru = Take/Receive (Borrow). Kasu = Give/Provide (Lend).

Another common error involves particle usage. Learners often use the particle と (to) instead of に (ni) or から (kara) when identifying the person they borrowed from. In English, we say 'borrow with someone' in very specific contexts, but in Japanese, the source is always a target (ni) or a starting point (kara). Saying 'Tanaka-san to hon o karita' would imply you and Tanaka-san went together to borrow a book from someone else, rather than you borrowing it from Tanaka-san himself. Precision with に is crucial for clear communication.

The 'Rent' Confusion

Don't use 'kariru' for things you hire (like a person). Use 'yatou' (hire) instead.

A subtle mistake is failing to use polite forms when borrowing from superiors. Simply saying 'Kariru yo' to a boss is incredibly rude. In Japanese, borrowing is a favor, so it should almost always be phrased as a request or with a benefit-receiving auxiliary verb like ~te morau or ~sasete itadaku. For example, 'Karisasete itadakimasu' (I will humbly be allowed to borrow this). Ignoring the social hierarchy when using kariru can lead to awkwardness or offense, as it might sound like you are entitled to the object.

Loanwords vs. Kariru

Using 'rentaru suru' is fine for businesses, but 'kariru' is more natural for friends.

Lastly, learners sometimes forget that kariru is an Ichidan verb and try to conjugate it like a Godan verb (e.g., saying 'karita' is correct, but some might mistakenly say 'karitta' or 'karimashita' is fine, but 'karimasu' is the only polite present form). Also, remember that kariru implies you will return the item. If you are taking something permanently (like a gift), use morau (to receive). If you are buying it, use kau. Using kariru for something you don't intend to return is not just a linguistic error, but a potential social misunderstanding. Always be clear about the 'return' aspect of kariru.

While かりる (kariru) is the most common word for borrowing, Japanese has several related terms that describe similar actions with different nuances. Understanding these can help you choose the most precise word for your situation. The most obvious related word is かす (kasu), which is the 'other side' of the transaction—to lend. Another important word is もらう (morau), which means 'to receive'. The difference is that morau implies the item is now yours, whereas kariru implies it must go back. If a friend gives you a cigarette, you morau it; if they let you use their lighter, you kariru it.

Kariru vs. Kasu

Kariru (Borrow/Take) vs. Kasu (Lend/Give). They are two sides of the same coin.

For formal or business situations, you will encounter 拝借する (haishaku suru). This is the humble version of kariru. It is used when you are borrowing something from someone of higher status, like a client or a boss. It shows extreme respect. On the other hand, 賃貸する (chintai suru) is a more technical term for 'leasing' or 'renting' in a legal or commercial sense, often seen in real estate contracts. While you might say 'heya o kariru' in conversation, the contract will say 'chintai'. There is also レンタルする (rentaru suru), which is specifically for commercial rental services like cars or equipment.

Kariru vs. Azukaru

Azukaru means 'to keep/hold onto' something for someone, without necessarily using it.

Another word often confused with kariru is 預かる (azukaru). While kariru means you take something to use it, azukaru means you are taking care of something for someone else. For example, if a friend asks you to hold their bag while they go to the restroom, you azukaru the bag. You are not 'borrowing' it because you aren't using it for your own benefit. Conversely, the friend is 預ける (azukeru)—entrusting the bag to you. These nuances are vital for correctly describing the flow of objects and responsibilities in Japanese society.

Loanword Nuances

リース (Riisu) is used for long-term business leases, like office copiers.

Finally, consider 借用する (shakuyou suru). This is a very formal, Sino-Japanese (Kango) version of kariru, mostly used in written documents or legal contexts. You might see it on a 'Borrowing Agreement' (Shakuyousho). For learners at the A2 level, focusing on the distinction between kariru and kasu is the priority, but being aware of morau and rentaru will help you navigate more complex conversations. Each of these words maps out the intricate ways Japanese people share resources, and choosing the right one shows a deep understanding of the social dynamics at play.
