Why was clemency trending last week?
early 15c., "an undertaking," from Old French enterprise "an undertaking," noun use of fem. past participle of entreprendre "undertake, take in hand," from entre- "between" (see entre-) + prendre "to take," contraction of prehendere (see prehensile). Abstract sense of "readiness to undertake challenges, spirit of daring" is from late 15c.
A business, generally a large one.
