Usage

What are other ways to say lack? The verb 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. Need often suggests urgency, 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.
