Morphology

necessary + evil

The phrase combines 'necessary' (required) with 'evil' (bad/unpleasant), so a B1 learner who knows both words can infer it denotes a bad or undesirable thing that must be accepted to achieve a better outcome. Although 'evil' is somewhat metaphorical here, the composition is straightforward and many languages have an equivalent expression, making the meaning readily derivable from the constituents.

Etymology

Necessary evil comes from joining necessary — meaning 'needed' — and evil — meaning 'bad' — to make a strong image. Imagine taking a bitter medicine you hate because it makes you well; that's why necessary evil means an unpleasant thing you must accept to get a better result.
