What does bellicose mean?
Bellicose is an adjective describing someone — or something such as a nation's policy — as aggressive, combative, and inclined toward fighting or war. A bellicose person is quick to quarrel and eager for confrontation; a bellicose speech or statement uses threatening, provocative language. The word derives from the Latin bellum, meaning "war," the same root that underlies "belligerent" and "rebellion," and it entered English in the early seventeenth century. It belongs chiefly to formal writing and public discourse: journalists and political commentators frequently describe leaders, governments, or rhetoric as bellicose when they appear to favour conflict over diplomacy. Because it implies a settled disposition toward aggression rather than a single act of hostility, calling someone bellicose is a pointed criticism. Its close relative "belligerent" overlaps in meaning but has an additional legal sense referring to parties actively engaged in war, while "bellicose" remains purely descriptive of temperament and tone.

Bellicose comes straight from the Latin word for "war" — the same root that gives us "belligerent" and even "rebel."

Etymology of bellicose
Bellicose comes from the Latin bellum, meaning "war," via the Late Latin bellicosus ("warlike, given to fighting"). It entered English in the early seventeenth century. It shares this root with related words such as "belligerent" and "bellicosity," and more distantly with "rebel" — from Latin rebellare, literally "to wage war again."
