Japanese [edit]

Etymology [edit]

From su (do). As with all verbs, during Middle Japanese the conclusive was gradually replaced by the attributive, realigning the conjugations.

Verb [edit]

する (irregular conjugation, kanji 為る, romaji suru)

  1. to do
    していますか。
    なにしていますか。
    Nani o shiteimasu ka?
    What are you doing?
  2. to wear (accessories)
    ネクタイする
    ねくたいする
    Nekutai o suru.
    To wear a necktie.

Usage notes [edit]

  • The verb する is seldom written in kanji (為る).
  • It is common to use する after certain nouns to indicate that the noun is being done; this is highly productive, meaning many verbs can be derived from nouns in this way, comparable to English -ly:
    失礼 (shitsurei, "rudeness") → 失礼する (shitsurei suru, "to commit a rudeness → to be rude")
    旅行 (ryokō, "journey") → 旅行する (ryokō suru, "to travel")

Synonyms [edit]

  • 〜る (-ru), a much less productive suffix for turning a noun into a verb
