Syn. 1. dearth, scarcity, paucity, deficit, insufficiency. 1, 3. want, need. 3. LACK, WANT, NEED, REQUIRE as verbs all stress the absence of something desirable, important, or necessary. LACK means to be without or to have less than a desirable quantity of something: to lack courage, sufficient money, enough members to make a quorum. WANT may imply some urgency in fulfilling a requirement or a desire: Willing workers are badly wanted. The room wants some final touch to make it homey.

NEED often suggests even more urgency than does WANT stressing the necessity of supplying what is lacking: to need an operation, better food, a match to light the fire. REQUIRE, which expresses necessity as strongly as NEED, occurs most frequently in serious or formal contexts: Your presence at the hearing is required. Successful experimentation requires careful attention to detail.

Ant. 1. surplus.
