- (colloquial, informal) good

Usage notes
- Most often written in this form. The kanji spelling 良い is generally reserved for more formal writing.
- This form does not inflect — it is only used in the 終止形 (shūshikei, “terminal form”) and 連体形 (rentaikei, “attributive form”) of ii. All other grammatical forms are based on 良い (yoi). Compare the 連用形 (ren’yōkei, “continuative or adverbial form”) yoku or the 過去形 (kakokei, “past tense”) yokatta; there is no *iku or *ikatta form.
- In ironic usages denoting “very bad” or “embarrassing”, this form is preferred to the yoi form.
