Syn. -- To Attack, Assail, Assault,
Invade. These words all denote a violent onset; attack being
the generic term, and the others specific forms of attack. To attack
is to commence the onset; to assail is to make a sudden and violent
attack, or to make repeated attacks; to assault (literally, to leap
upon) is to attack physically by a had-to-hand approach or by unlawful and
insulting violence; to invade is to enter by force on what belongs
to another. Thus, a person may attack by offering violence of any
kind; he may assail by means of missile weapons; he may
assault by direct personal violence; a king may invade by
marching an army into a country. Figuratively, we may say, men
attack with argument or satire; they assail with abuse or
reproaches; they may be assaulted by severe temptations; the rights
of the people may be invaded by the encroachments of the crown.
