Synonyms Attempt, Essay, Undertake, Endeavor, Strive, Struggle, seek, aim. The italicized words agree in expressing the beginning of a task, physical or intellectual, which is difficult and often impossible. They are arranged in the order of strength. Attempt is to try with some effort. Essay is sometimes to try in order to see if a thing can be done or attained, and sometimes simply to attempt: as, “which the Egyptians assaying to do were drowned,” Heb. xi. 29. Undertake is, literally, to take a task upon one's self, perhaps formally, and hence to go about a task with care and effort. Endeavor is to try with more earnestness, labor, or exertion. Strive is to work hard and earnestly, doing one's best. Struggle is to tax one's powers to the extent of fatigue, pain, or exhaustion. The first three words are more appropriate for a single effort, the other three for continuous or continual efforts.
