Noun

1. a purchase, the act of buying something

Verb

購入する ‎(hiragana こうにゅうする, romaji kōnyū suru, historical hiragana こうにふする)

1. to purchase

Conjugation

Usage notes

Just as with English purchase compared to buy, the Chinese-derived 購入する (kōnyū suru) is more formal than the native Japanese term 買う (​kau). This is an example of the usual formality difference between kango terms versus native Japanese terms (大和言葉 ‎(Yamato kotoba)).

Synonyms

• 買 (か)う ‎(kau)
