Usage

Mitigate is sometimes wrongly used where militate is meant: his behaviour militates (not mitigates ) against his chances of promotion

Commonly Confused

Mitigate, whose central meaning is “to lessen” or “to make less severe,” is sometimes confused with militate, which means “to have effect or influence; weigh on.” This mix-up often occurs in the use of the phrase mitigate against, as follows: This criticism in no way mitigates (read militates ) against your going ahead with your research. Although this use of mitigate occasionally occurs in edited writing, it is rare and is widely regarded as an error.

Etymology

Origin of mitigate

First recorded in 1375–1425; late Middle English mitigaten, from Latin mītigātus (past participle of mītigāre “to calm, soften, soothe”), equivalent to mīt(is) “mild, soft, gentle” + -ig- (combining form of agere “to do, cause to do, make”) + -ātus verb suffix; see -ate ¹

Explanation

Choose the verb mitigate when something lessens the unpleasantness of a situation. You can mitigate your parents' anger by telling them you were late to dinner because you were helping your elderly neighbor. The somewhat formal verb mitigate comes from the Latin roots mītis, "soft," and agere, "to do/act," which add up to "to soften." It is often used with words that indicate an outcome or something harmful. When you buy car insurance, you are trying to mitigate the risks involved with driving. Sunscreen is used to mitigate the effects of the sun on your skin.
