Usage Note

Synonym discussion

Sense: adjective/1

All four words describe closeness to fact, but they differ in scope and formality. 'Correct' is the most general term for a single answer, calculation, or piece of information ('the correct time is 3 PM'). 'Accurate' emphasises exactness and freedom from error, often used with measurements, reports, or descriptions ('an accurate account of the events'). 'Right' is more informal and overlaps with 'correct', but also carries a moral flavour ('the right thing to do'). 'Truthful' focuses on the honesty of a person or statement rather than precision ('a truthful witness gives honest answers'). 'True' (sense 1) sits between them: it describes a statement that matches reality, often with a broader sense of reliability than 'correct' or 'accurate'. For example: 'The weather forecast was correct about the rain' (factually right); 'The map is accurate to within one metre' (exact); 'She gave a truthful account of what she saw' (honest); but 'Everything he said turned out to be true' (matched reality as a whole).

Etymology

Proto-GermanicOld EnglishMiddle EnglishEnglish

The word 'true' comes from Old English 'trēowe', which meant 'faithful' or 'trustworthy' — a quality of a person, not a statement. It is related to 'troth' (a pledge of loyalty, as in 'plight one's troth'). The meaning broadened over time: from personal loyalty (still seen in 'true friend') to factual accuracy ('a true story') to physical alignment ('straight and true'). The root goes back to Proto-Germanic *trewwjaz, and further to an Indo-European root meaning 'tree' or 'firm' — suggesting steadfastness like a tree. Cognates include German 'treu' (faithful) and Dutch 'trouw' (loyal).
