lassant

Lassant is the masculine present participle of the French verb lasser, meaning to tire or weary. When used as an adjective, lassant describes something that causes weariness or is tiresome; the feminine form is lassante, as in une tâche lassante (a tiresome task). As a participle, it can function within tenses or as a reduced relative clause in French.

In English-language contexts, lassant is rare and mostly encountered in translations or linguistic discussions. English speakers typically render the sense with tiresome, wearying, or tedious rather than borrowing the participle form.

Etymology traces the word to the French verb lasser, which itself derives from the Latin lassus meaning weary. The present participle is formed with the standard -ant ending, following regular French morphology.

Usage notes: Lassant should not be used as a noun; it remains an adjective or participle. It commonly appears in descriptions of work, tasks, or situations that drain energy or fail to hold interest.
