What does fishier mean?
"Fishier" is the comparative form of the adjective "fishy," used chiefly to describe something that seems increasingly suspicious, deceptive, or untrustworthy. When a story grows "fishier" with each retelling, listeners are signalling growing doubt about its truth. The word carries distinctly negative connotations — it implies that someone may be hiding something or acting in bad faith — yet its tone is often colloquial and even lightly humorous, making it common in conversation, journalism, and casual commentary rather than formal writing. A secondary, literal sense refers to a stronger smell or taste of fish, as when a seafood counter becomes "fishier" through the day. Derived ultimately from the Old English noun "fisc" (fish), the underlying adjective "fishy" has carried its figurative sense of doubt for centuries, showing how a simple sensory association can harden into a metaphor for distrust. Knowing "fishier" equips readers to express escalating scepticism with vivid, idiomatic economy.

"Fresh fish should never smell fishier than the sea itself."
When a story smells bad but no one has actually caught anything, English speakers reach for "fishier" — a word whose figurative use dates back centuries and shows how deeply fish became shorthand for doubt.

Etymology of fishier
The word traces back to "fishy," an adjective formed from "fish," which descends from Old English "fisc," a common Germanic noun with cognates such as German "Fisch" and Dutch "vis." The suffix "-y" formed adjectives meaning "characteristic of" or "resembling" their base noun, so "fishy" originally meant smelling or tasting of fish. Its figurative sense — suggesting something dubious or unreliable — developed later, becoming well established in English usage by at least the early modern period. Related words sharing the fish root include "fishery," "fisher," and "fishmonger," which denote activities, people, and trades connected with fish rather than states of suspicion.

"Fishier" is informal to neutral in register and appears almost exclusively in speech and journalistic writing rather than formal legal or academic prose. The figurative sense (arousing suspicion) far outweighs the literal olfactory sense in everyday use. As a comparative, it requires a basis of comparison, whether explicit ("fishier than") or implied by context.
