An armistice is a formal agreement of warring parties to stop fighting.
It is not necessarily the end of a war, as it may constitute only a cessation of hostilities while an attempt is made to negotiate a lasting peace.
[1] It is derived from the Latin arma, meaning "arms" (as in weapons) and -stitium, meaning "a stopping".
