ことにする (kotonisuru)

to make the decision to do something

Meaning & usage

ことにする expresses a decision made by one's own will to do something or not do something. It follows the dictionary form of a verb for an affirmative decision, as in 勉強することにした, and the ない form for a negative decision, as in 行かないことにした. The tense matters: ことにした reports a past decision, ことにしている describes a continuing habit or personal rule, and ことにしよう proposes making a decision together.
