Mitigate vs. Militate: Usage Guide

Mitigate is sometimes used as an intransitive (followed by against) where militate might be expected. Even though Faulkner used it

some intangible and invisible social force that mitigates against him

—William Faulkner

and one critic thinks it should be called an American idiom, it is usually considered a mistake.

Did you know?

The meaning of mitigate is straightforward enough: to make something—such as a problem, symptom, or punishment—less harsh or severe. Sometimes, however, mitigate appears where the similar-looking militate is expected. That word, which is often followed by against, means “to have weight or effect,” as in “your unexcused absences are likely to militate against your getting a promotion.” The two words are not closely related (mitigate comes from the Latin verb mitigare, meaning “to soften,” whereas militate traces to militare, meaning “to engage in warfare”), but the confusion between the two has existed for long enough that some usage commentators have accepted “mitigate against” as an idiomatic alternative to militate. Even William Faulkner used mitigate in this way in his 1932 short story, Centaur in Brass, writing “It's as though there were some intangible and invisible social force that mitigates against him.” But unless you’re Faulkner, it’s best to keep mitigate and militate distinct.
