hesitation

n. hesitating, pausing; stammering, faltering

Hesitation is the act of pausing due to indecision or uncertainty, in either speech or action.According to a proverb, "He who hesitates is lost." This is generally taken to be a caution to avoid hesitation, because it may cause an opportunity to be lost entirely.Instances of hesitation in literature include the soliloquies of the character Prince Hamlet, in the play by Shakespeare.
