一いっ家かを成なす

expression, godan verb (-su)

establish oneself as an authority; found a school of thought; make a name for oneself

Used when someone becomes a recognized expert or leader in a field, creating their own distinctive style or school. The literal meaning 'to make a home of one's own' is less common in modern usage; the idiomatic sense of professional or intellectual independence is primary.
