What does agonise mean?
To agonise is to experience intense, often prolonged mental suffering, most commonly over a difficult decision, dilemma, or troubling situation. Someone who agonises does not merely worry briefly; they turn a problem over repeatedly, feeling genuine anguish until it is resolved. The verb also has an older, less frequent sense describing physical struggling in extreme pain. Derived from the Greek 'agon', meaning contest or struggle, the word retains that sense of hard-fought inner conflict. It is used in both everyday and formal contexts — someone might agonise over a career choice, a confession, or a medical diagnosis. The spelling varies regionally: British English favours 'agonise' with an s, while American English uses 'agonize' with a z. Because the word implies deep emotional investment, it is stronger than simple synonyms like 'worry' or 'fret', and it is best reserved for situations involving real torment or high stakes.

Etymology of agonise
Agonise derives from the Greek 'agonia', meaning a struggle or contest, which itself comes from 'agon', the term for the athletic and dramatic competitions of ancient Greece. The word passed into Latin as 'agonia' and then entered English via French in the late Middle Ages, initially referring to severe physical suffering such as the agony of death. Over time its meaning broadened to include intense mental anguish, which is now its dominant sense. Cognates include 'agony', 'antagonist', and 'protagonist', all tracing back to the same Greek root of struggle and contest.
