What does loosest mean?
Loosest is the superlative form of the adjective loose. It identifies something as more loose, slack, open, or unrestricted than anything else in a comparison. Its physical sense is commonly used of clothing, ropes, wires, fittings, or other objects that are not tightly secured: the loosest rope in the bundle, for example, or a garment with the loosest fit. In figurative contexts, loosest can describe the least restrictive rule, the most permissive interpretation, or the weakest degree of precision. The word is neutral and common in both British and American English. Its usefulness lies in expressing an absolute comparison without requiring the reader to reconstruct the full relation from looser and loose. Although “most loose” is sometimes used informally, the established form is loosest, with the superlative ending -est attached directly to loose.
