Syn. -- To vex; harass: annoy; disturb; irritate; plague; torment; mortify; tantalize; chagrin. -- Tease, Vex. To tease is literally to pull or scratch, and implies a prolonged annoyance in respect to little things, which is often more irritating, and harder to bear, than severe pain. Vex meant originally to seize and bear away hither and thither, and hence, to disturb; as, to vex the ocean with storms. This sense of the term now rarely occurs; but vex is still a stronger word than tease, denoting the disturbance or anger created by minor provocations, losses, disappointments, etc. We are teased by the buzzing of a fly in our eyes; we are vexed by the carelessness or stupidity of our servants. [ 1913 Webster ]
