The most fragile, delicate, or physically weak; the superlative form indicating the greatest degree of frailty.
Superlative form of 'frail', using the '-est' suffix. From Middle English 'frail' via Old French 'fraile', ultimately from Latin 'fragilis' (breakable).
English uses both '-est' (frailest) and 'most frail' for the superlative, but the '-est' form connects directly to our oldest Germanic language patterns, making it literally a more 'native' way to say it!
