## AI Etymology
Fishy comes from fish + -y; the 'suspicious' sense is a nineteenth-century figurative extension, possibly from the idea of something that 'smells fishy' or from the wary, slippery nature of fish. Morphologically, the account is both compositional and suffixal: -y marks the visible structure by which the older base becomes the modern form. In present use, it is used as an adjective meaning "arousing suspicion; of doubtful character", so the historical material remains connected with the current sense rather than standing as bare ancestry. The wider English family includes derivatives such as fishily and fishiness and related forms such as fish, showing how the same historical material continues to organize neighboring vocabulary. The named historical forms include Old English fisc and Proto-Indo-European *peysk-, keeping the history tied to concrete forms rather than a loose resemblance.
