Inimical
ih-NIM-ih-kul
Definition
(adjective) Likely to cause harm or work against something; hostile and damaging to a person or cause.
Example
The startup’s chaotic management style proved inimical to creativity, driving away the very talent it needed most to survive.
Word Origin
Inimical derives from the Latin inimicalis, meaning “hostile” or “unfriendly,” rooted in inimicus — “enemy” — built from in- (“not”) and amicus (“friend”). It shares its ancestry with the word enemy, both tracing back to the same Latin root. It entered English in the 17th century, used to describe forces, conditions, or people that actively work against something rather than simply being indifferent to it.
Fun Fact
The Latin amicus — friend — sits at the root of a surprisingly large family of English words. Amiable, amicable, amity, and even amateur (originally meaning one who does something out of love) all share the same ancestor. Inimical is the dark twin of this family — the “un-friend,” so to speak — which makes it one of the rare words whose etymology tells you exactly what it means the moment you know its root. Linguists call this kind of transparent etymology a “motivated” word, where the meaning feels inevitable once the parts are understood.
