The superlative form of 'bold,' meaning the most brave, daring, or confident.
From Old English 'bald' (meaning brave) with the superlative suffix '-est,' which marks the highest degree of an adjective (as in 'fastest,' 'brightest,' 'strongest').
The '-est' suffix is one of English's oldest grammatical patterns—it comes from Proto-Germanic and shows up in superlatives across all Germanic languages, making 'boldest' a word with thousands of years of linguistic ancestry!
