意味

A moment; an instant; a brief period of time. Also used as a na-adjective meaning stubborn or headstrong.

The temporal meaning appears in expressions like 一刻も早く (as soon as possible; without a moment's delay). The secondary meaning of stubborn or obstinate applies to a person's character, as in 一刻者 (a headstrong person). Context determines which reading is intended. Both uses are found at N1 level.
