What does exterminable mean?
"Exterminable" is a formal adjective meaning capable of being exterminated — that is, able to be destroyed or wiped out completely. It derives from the Latin verb "exterminare", literally to drive beyond one's boundaries, which passed into English as "exterminate" in the sixteenth century. The adjective is uncommon in everyday speech, appearing most often in discussions of pests, vermin, invasive species, or metaphorically about undesirable ideas and institutions. Saying an infestation is "exterminable" asserts confidently that total eradication is achievable rather than merely controllable. The word carries a somewhat clinical, decisive connotation, implying finality: whatever is exterminable can, in principle, be ended for good. Its negative counterpart, "inexterminable", describes something stubbornly impossible to eliminate. Writers reach for it when they want precision and gravity beyond simpler alternatives such as "removable" or "curable". While rare, it is transparent to readers familiar with "exterminate", making it a useful, exacting choice in technical prose and deliberate rhetoric alike.

The same Latin root that gives us "terminus" — the end of the line — hides inside "exterminable": to be exterminated is, quite literally, to be driven past your boundaries and out of existence.

Etymology of exterminable
"Exterminable" comes from Late Latin "exterminabilis", formed from "exterminare", meaning to drive out or expel beyond boundaries, itself from "ex-" (out) and "terminus" (boundary, limit). English adopted "exterminate" from the Latin verb in the late sixteenth century, with senses shifting from expulsion toward outright destruction, and the adjective "exterminable" followed as a natural derivative. It shares its root with words such as "terminate", "terminal", and "terminus".
