Aggravate and worsen both push a bad thing further down, but they differ on who is pushing. Aggravate needs an outside hand: something or someone works the condition worse — running aggravates the sprain, a remark aggravates the row. Worsen is neutral and self-sufficient: things can simply worsen on their own — the weather worsened, her eyesight worsened. Aggravate points a finger; worsen just reports the slide.
Both verbs chart decline, and grammar splits them cleanly. Aggravate, from the Latin aggravare, 'to make heavier', is transitive to the bone: there is always an aggravator, and often a reproach in the word — the worsening did not have to happen. Worsen is plain English built on 'worse' and works both ways: tariffs can worsen a shortage, but a shortage can also just worsen, agentless, the way weather turns. When you know what did the damage, aggravate names it; when the line on the chart simply drops, worsen.
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.
worsen
To worsen is the plainest way English has of saying that bad is heading toward worse — and, tellingly, it needs no one to blame. Weather worsens, a patient's condition worsens, a shortage worsens: the verb works intransitively, for things that slide downhill by themselves, which sets it apart from aggravate, where an outside action does the damage. It also works transitively — a badly timed policy can worsen the very problem it was meant to cure. Neutral in register, it fits everywhere its formal cousins exacerbate and deteriorate would sound heavy.

Ask whether you can point at the culprit. The man bouncing on his own bandaged ankle until the throb stays huge — a hand did that, and the word carries the blame: aggravate. The picnic sky that sours cloud by cloud with no one to accuse — the day simply slid: worsen. If there is a finger to point, aggravate; if it just got worse, worsen.
aggravate
- iLifting the boxes aggravated her back problem.
- iiThe mayor's tone aggravated an already angry crowd.
- iiiScratching only aggravates the bite.
worsen
- iTraffic worsens every year despite the new lanes.
- iiThe drought worsened the food shortage.
- iiiHis condition worsened suddenly in the night.
In transitive sentences they overlap — 'the drought aggravated/worsened the shortage' both work, aggravate adding a touch of reproach, worsen staying neutral. But only worsen can drop the object entirely: conditions worsen, weather worsens, relations worsen. And only aggravate reaches people's nerves: an aggravating colleague is annoying, never a 'worsening' one.
