What does sceptic mean?
A sceptic is someone who questions whether a statement, belief, or supposed fact is true or convincing. The word can describe a careful person who asks for evidence, but it can also describe someone who habitually challenges authority, conventional opinion, or promotional claims. In ordinary use, scepticism often suggests intellectual independence and a preference for verification over credulity, although the word can carry a faintly negative tone when it implies excessive distrust. The British spelling is 'sceptic', with 'skeptic' being the standard US spelling; the related adjectives are 'sceptical' and 'skeptical'. The term is useful in discussions of philosophy, science, politics, advertising, and everyday judgment, where claims are being evaluated rather than accepted automatically. Its history is especially memorable because the original Greek term referred not to someone who rejected knowledge, but to someone who examined and investigated it.
nounA person who questions or doubts the truth, validity, or likelihood of a claim, especially someone who is inclined to challenge accepted opinions. A sceptic may simply require evidence, or may adopt a more strongly critical or distrustful attitude toward a claim.
- A person who questions or doubts a claim, theory, or accepted opinion.
- A person who generally distrusts conventional beliefs or promotional claims and expects strong evidence before accepting them.

The word comes from the Greek skeptikos, an inquisitive person who followed inquiries rather than blindly accepting claims.

Where does sceptic come from?
The English word derives from Latin scepticus, from Greek skeptikos, an adjective meaning 'inquisitive' or 'able to investigate'. The Greek word was associated with philosophical inquiry and with those who suspended judgment while examining competing explanations. English borrowed the term in the 17th century, initially in contexts connected with philosophical doubt and skepticism before broadening to include ordinary people who question claims or accepted beliefs. The spelling variation reflects the later influence of Greek-derived forms in British English and the different general convention of spelling with -sk- in US English.
How sceptic is actually used
The term is neutral to mildly critical in most contexts and can suggest either careful, evidence-based doubt or a broader disposition to distrust claims. In British English, 'sceptic' is standard, while US English generally uses 'skeptic'; the closely related adjective is 'sceptical' in British English and 'skeptical' in US English.
