Mitigate and relieve both take the harshness out of something bad, at different moments. Mitigate limits the severity of harm — often before or as it lands: you mitigate risks, damage, impacts. Relieve lifts a burden that is already pressing on someone — pain, pressure, stress — enough for the release to be felt. Mitigate softens the blow; relieve takes the load off after it has landed.
Both verbs stand between someone and the full weight of something bad, and the timing tells them apart. Mitigate, from the Latin mitigare, 'to make mild', works on the harm itself, usually ahead of it: defences, precautions, and policies mitigate what has not finished happening. Relieve, from relevare, 'to lift again', works on the sufferer, always after the weight is on: the load exists, presses, and is then taken off — with the exhale to prove it. One word prepares; the other rescues.
mitigate
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).
relieve
To relieve is to lift a burden, pain, or distress off someone — enough that what remains is bearable. An aspirin relieves a headache; a good laugh relieves tension; a new road relieves congestion on the old one. The word centres on the felt moment of release: pressure that was bearing down comes off, and you breathe again. It shares ground with alleviate and lessen, but relieve stresses removal rather than mere reduction — and it has a second life in taking over someone's post, as when a fresh guard relieves the one on duty.

Put the two scenes on a timeline. The awning goes out before the flowerpot ever tips, so the fall ends in a hairline crack — the harm met in advance and made milder: mitigate. The sack is already crushing the man when the helper hoists it away and his chest fills — the burden lifted after it landed: relieve. Prepare the defence → mitigate; deliver the release → relieve.

They meet in crisis prose — you can mitigate or relieve the effects of a drought — and the timeline chooses: mitigation was in place or swiftly mounted against the harm; relief reaches the people already under it (which is why aid is 'relief', never 'mitigation'). Only mitigate has the legal and climate senses; only relieve has the felt adjective ('relieved'), the duty-swap ('relieve the guard'), and the pattern 'relieve someone of something'.
A timeline pair for essays: propose measures that 'mitigate the risk/impact' (prevention), then describe how they 'relieve the pressure/burden' on people (felt outcome) — using both in one paragraph reads as precise planning. Fixed phrases split cleanly: 'mitigating circumstances' and 'climate mitigation' versus 'disaster relief', 'pain relief', and 'to my relief'. In Listening, 'relieve someone of their duties' is the polite removal from a job; nothing is ever 'mitigated of' anything.
