Everyone needs a “word of the day” Today mine is “Polemic”

A polemic (pron.: /pəˈlɛmɪk/) is a contentious argument that is intended to establish the truth of a specific belief and the falsity of the contrary belief. Polemics are mostly seen in arguments about very controversial topics.

The art or practice of such argumentation is called polemics.

A person who often writes polemics, or who speaks polemically, is a polemicist or a polemic.[1] The word is derived from the Greek πολεμικός (polemikos), meaning “warlike, hostile”,[2][3] which comes from πόλεμος (polemos), “war”.[4]
