At large; in general or overall; also, in a nautical context, away from land or at sea.
From Middle English and Old French, combining 'a' (at) with 'large,' originally meaning 'at liberty' or 'free,' evolving to mean 'in general' or nautically 'at sea.'
The phrase 'at large' comes from this word, and it's why when a criminal escapes prison, police announce they are 'still at large'—it's literally saying they're free and unfound in the general population.
