Notes
GENERAL INFO
guerre (f. noun) means "war" or "warfare". It refers to a state of armed conflict between different countries, groups, or within a country.
USAGE
It's commonly used with the definite article "la" or indefinite "une". You'll see it in phrases like "déclarer la guerre" (to declare war), "une guerre civile" (a civil war), or "être en guerre" (to be at war).
TRAPS
Remember guerre is feminine: *une* guerre, *la* guerre. Do not confuse it with "guère," which is an adverb meaning "hardly" or "barely." For example, "Il n'a guère de temps" (He hardly has any time).
