2. Done feebly and without conviction.
3. Dizzy or weak, as if about to become unconscious.
4. Etymology: "lacking in courage", now mostly in faint-hearted (mid-15th century), from Old French feint, "soft, weak, sluggish"; the past participle verb form of feindre, "hesitate, falter, be indolent, show weakness, avoid one's duty by pretending".
Don't confuse the spelling of faint and feint, which have similar sounds.
Faint, the more frequent in usage of the two words, can be used as an adjective meaning "dizzy, weak" or "slight"; such as, in "to feel faint, a faint smell, a faint chance"; or as a noun or verb referring to a sudden loss of consciousness.
Feint is a noun or verb referring to "a deceptive action in a sport" or "in combat".
