purpose clause; final clause; object clause
A grammatical term for a clause that expresses the purpose or goal of an action. In Japanese linguistics, it often refers to clauses marked by ために, のに, or ように. The gloss 'object clause' is less common in English grammar but may appear in some Japanese pedagogical contexts.
In 'I went to Japan to study Japanese,' the phrase 'to study Japanese' is a purpose clause.
Purpose clauses often use 'tame ni' or 'yō ni'.
