False etymologies are a consequence of the longstanding interest in putatively original, and therefore normative, meanings of words, a characteristic of logocentrism. Until academic linguistics developed the comparative study of philology and the development of the laws underlying sound changes, the derivation of words was a matter mostly of guess-work, sometimes right but more often wrong, based on superficial resemblances of form and the like. This popular etymology has had a powerful influence on the forms which words take (e.g., crawfish or crayfish, from the French crevis, modern crevisse, or sand-blind, from samblind, i.e. semi-, half-blind), and has frequently been the occasion of homonyms resulting from different etymologies for what appears a single word
