to make something less severe, harmful, or painful

01Definition

To mitigate is to soften a blow you cannot entirely prevent. Sea walls mitigate flooding; apologies mitigate anger; insurance mitigates financial loss. The word concedes that the bad thing exists or will happen — the work of mitigation is to reduce its severity, not to eliminate it. This is why climate policy distinguishes mitigation (cutting emissions to lessen warming) from adaptation (living with the warming that comes anyway).

06TOEFL & IELTS

One of the most useful verbs in academic English. IELTS Writing Task 2 problem-solution essays practically require it: 'To mitigate this problem, governments could…'. TOEFL passages on climate and public health use 'mitigation' as a key term. Don't confuse it with 'militate against', a classic usage trap.

07Asked
Is 'mitigate against' correct?
Careful usage says no. Mitigate takes a direct object — you mitigate a risk, not against it. The stray preposition sneaks in from militate against, a different verb meaning to weigh or work against something ('the evidence militates against that reading'). The roots keep them apart: mitigate is from mitis, 'mild'; militate from miles, 'soldier'. Usage guides have policed the mix-up for a century, and exams side with the guides.
What are mitigating circumstances?
Facts that lower blame without erasing the offence — the courtroom's version of softening a blow that has already landed; they are unpacked against their opposite on the aggravate vs mitigate page in the 'Compared' list above.
Does mitigating a risk mean preventing it?
No — prevention stops the event; mitigation accepts that it may happen and blunts what it costs. Risk plans run both lanes: prevent what you can, mitigate what you cannot. The scene above keeps the two honest: the awning was cranked open before anything went wrong, yet it never stops the flowerpot from falling — it only makes the landing survivable, a single crack where there would have been pieces.
What is mitigation in climate policy?
Cutting emissions at the source, so that less warming arrives at all. Its policy counterpart is adaptation, which redesigns farming, coasts and cities around the change already locked in — one lane shrinks the problem, the other reshapes life to fit it. How mitigate sits beside its gentler neighbours is mapped on the ease vs mitigate page in the 'Compared' list above.
What does the 'duty to mitigate damages' mean?
A rule of law: the injured side must take reasonable steps to stop its losses from growing, because compensation covers what could not be helped, not what was allowed to accumulate. In most common-law systems a wrongfully dismissed employee is expected to seek work, and a landlord is usually expected to try to re-let. The legal phrase keeps the word's core promise — the harm exists; your job is to keep it small.
