Notes
GENERAL INFO
mort can be an adjective meaning "dead" (e.g., *Il est mort.* - He is dead.) or a noun meaning "death" (f.) or "a dead person/animal" (m./f.).
USAGE
As an adjective, it agrees in gender and number: *une plante morte*, *des animaux morts*. As a noun: *La mort est inévitable.* (Death is inevitable.) *Les morts sont partis.* (The dead have left.)
TRAPS
As a noun, "la mort" (feminine) refers to the abstract concept of death. "Un mort" (masculine) or "une morte" (feminine) refers to a deceased person. Do not confuse with the verb "mourir" (to die).
