How it's used

This term is specifically used to describe involuntary muscle contractions or seizures, often associated with high fevers in children. It carries a sense of urgency and alarm, as it is almost always used in medical or emergency contexts. You will rarely hear it used in a metaphorical sense, unlike some other languages where similar words might describe excitement or agitation.

Examples

He is having a convulsion, call an ambulance quickly!
After the child finished convulsing, he seems very tired now.

Common phrases

to have a convulsion

Common mistake

Learners often confuse this with general shaking or trembling, but it specifically refers to medical convulsions or seizures. Do not use it to describe someone shivering from cold or fear, as those situations require different verbs.
