Origin of adequate

First recorded in 1610–20; from Latin adaequātus “matched” (past participle of adaequāre ); see ad-, equal, -ate 1

Explanation

When you want to say that something is enough or good enough for a particular need, use the adjective adequate. You might have an adequate amount of flour for a batch of pancakes, but not a lot extra. Adequate can also describe something that is acceptable or satisfactory, but not any better than that. You might say that a student's grades are adequate but need improvement. This word is from Latin adaequāre"to make equal," from the prefix ad- plus aequare "to equal."
