Understanding the Meanings: Kaesu vs. Henkyaku suru
Kaesu (返す): The Everyday “Return”
Kaesu is a commonly used verb in Japanese that means “to return” or “to give back.” It is usually written in kanji as 返す and is used in everyday situations when returning something to its original owner. This verb is informal and straightforward, making it suitable for conversations with friends, family, or people of similar social status.
Henkyaku suru (返却する): The Formal “Return”
Henkyaku suru is a more formal expression, often used in official or business contexts. The kanji 返却 (henkyaku) implies the act of returning something that has been borrowed, such as library books, rental items, or equipment. The addition of する turns it into a verb phrase, meaning “to return (an item formally or officially).” This term is appropriate when dealing with institutions or in written communication.
Contextual Usage: When to Use Kaesu
Use kaesu when you are:
- Giving back something to a friend or family member.
- Returning a favor or gesture.
- In informal settings, such as casual conversations.
Example sentences:
- 友達に本を返す。
Tomodachi ni hon wo kaesu.
(I return the book to my friend.) - 彼女にお金を返した。
Kanojo ni okane wo kaeshita.
(I gave the money back to her.)
Contextual Usage: When to Use Henkyaku suru
Use henkyaku suru when you are:
- Returning something to an institution, like a library or rental store.
- Filling out official documents or speaking in business situations.
- In formal writing or announcements.
Example sentences:
- 図書館に本を返却する。
Toshokan ni hon wo henkyaku suru.
(I return the book to the library.) - レンタカーを返却しました。
Rentakaa wo henkyaku shimashita.
(I returned the rental car.)
Grammatical Differences and Politeness Levels
Another key difference between kaesu and henkyaku suru is the level of politeness. While kaesu can be made polite by using its masu-form (返します, kaeshimasu), it still retains its informal nuance compared to henkyaku suru. The latter is inherently more formal, and when used in its polite form (返却します, henkyaku shimasu), it fits seamlessly into business and institutional interactions.
Common Mistakes and How to Avoid Them
Japanese learners often mistakenly use kaesu in formal situations or henkyaku suru in everyday conversations, which can sound unnatural. To avoid this:
- Remember: kaesu is for people, informal exchanges, or personal belongings.
- Use henkyaku suru for formal settings, institutions, or when dealing with organizations.
