What does commonest mean?
"Commonest" is the superlative form of the adjective "common," used to identify whichever member of a set occurs most frequently or is most widely found. A doctor might say that headaches are the commonest symptom of dehydration; a birder might note that the robin is the commonest visitor to garden feeders. The word carries no judgment about quality — calling something the commonest says only that it appears most often, though in some contexts "common" can shade toward connotations of ordinariness. Both "commonest" and "most common" are grammatically standard, with "commonest" favored where concision is valued and "most common" often preferred in very formal prose. The word is especially at home in scientific, medical, and statistical writing, where ranking things by frequency is routine. Its ultimate root is the Latin "communis," meaning shared or public, which also gives English words like "community" and "communicate" — a reminder that what is common is, literally, what is held in common by many.

Etymology of commonest
"Commonest" derives from "common," which entered Middle English from Old French "comun," itself borrowed from Latin "communis," meaning shared by all or public. The superlative suffix -est is a native English formation, so the whole word is built on Romance roots with Germanic inflection. Its Latin parent also yields English cognates such as "community," "communicate," and "communal," all preserving the sense of sharing or being held in common.
