aggravate vs exacerbate
Aggravate and exacerbate both mean to make a bad thing worse, and in most sentences either works. The differences are tendencies: aggravate often implies a careless or deliberate hand — and, with injuries, a lasting worsening (you aggravate a sprain by running on it) — and informally it also means to annoy. Exacerbate is more formal, often accidental, and paints a flare-up: a problem intensified. A wound worked worse versus a problem inflamed.
Quick rule: an injury (or a person's patience) worked worse, often lastingly → aggravate; a situation intensified into a flare-up, formal → exacerbate.
A man with a bandaged ankle and a small, bearable red pulse gets up and bounces on the bad foot; every landing flashes red and jumps the pulse up a size, until he drops back onto the stool clutching his shin — and the throb stays huge. His own careless hand made it lastingly worse.
/ˈæɡrəveɪt//ˈæɡrəveɪt/·verbA patient in a sickbed takes a spoon of medicine and swallows it — but instead of relief it backfires: fever floods the face, one small throb multiplies into a ring of sharp ones, and the wince twists into a gasping grimace as the illness flares worse.
/ɪɡˈzæsərbeɪt//ɪɡˈzæsəbeɪt/·verbThese two are the classic pair of worseners, and their roots split the flavour. Aggravate comes from the Latin aggravare, 'to make heavier' (gravis, 'heavy'): weight pressed onto what already hurts, which is why it owns injuries — you aggravate a hamstring, a hernia, an old wound — and why the worsening feels lasting. Exacerbate comes from exacerbare, 'to make bitter' (acerbus, sharp-bitter, as in acerbic): the situation is soured and inflamed, often by something well-intentioned, which is why policies, remarks, and shortages get exacerbated. Aggravate also moonlights as 'annoy' in speech — a use exacerbate never picked up.
What each means
aggravate
To aggravate something is to make a bad thing worse — and the word points a finger while it says so. A condition that is aggravated did not simply deteriorate; some outside action worked on it, often a careless or deliberate one: running on a sprained ankle aggravates the injury, a harsh reply aggravates a quarrel. The worsening tends to stick. Its mirror-opposites are alleviate, relieve and ease, and its close cousin is exacerbate, which is more formal and often accidental. In everyday speech aggravate has a second job: to annoy or irritate someone, usually through repetition.
exacerbate
To exacerbate is to make a bad thing worse — the exact mirror of mitigate. The Latin exacerbare means 'to make bitter' (acerbus is the root of 'acerbic'), and the word's particular cruelty is that it so often describes help gone wrong: scratching exacerbates the itch, hasty fixes exacerbate the bug, emergency borrowing exacerbates the debt. What exacerbates rarely intends to — which is why the word travels with 'only', as in measures that only exacerbated the crisis.

How to remember the difference
Two ways to make things worse. The man who bounces on his own bandaged ankle until the throb stays huge — weight added to what already hurt, by a hand that should have known better — that is aggravate. The spoonful of medicine that backfires, fever flooding, the illness flaring — a situation soured and intensified — that is exacerbate. Injuries and irritations are aggravated; crises and tensions are exacerbated.
Examples
aggravate
- He aggravated the old knee injury in the warm-up.
- Their constant humming aggravates everyone in the office.
- Cutting the night buses aggravated the isolation of the estate.
exacerbate
- The leak exacerbated tensions between the two ministries.
- Poor drainage exacerbated the flooding downstream.
- Her joke, meant to defuse things, only exacerbated the row.
With abstract problems the two overlap almost completely — tensions, shortages, and crises can be aggravated or exacerbated, exacerbate sounding a notch more formal. Two zones do not overlap: physical injuries take aggravate ('exacerbate a sprain' sounds clinical at best), and the informal sense of annoying a person belongs to aggravate alone — no one is ever 'exacerbated' by their neighbour's trumpet.
In TOEFL & IELTS
Both are high-band verbs for cause-effect writing; 'exacerbate the problem/inequality/tensions' is the essay staple, while 'aggravate an injury' is the collocation examiners expect in health topics. In legal and formal Reading, 'aggravating circumstances' (worsening blame) contrasts with 'mitigating circumstances'. Keep the informal 'aggravate = annoy' for Speaking only, and mind both spellings: agg-ra-vate (no 'i'), ex-acerb-ate (as in acerbic). Pronounce exacerbate ig-ZAS-er-bate.
