sceptical
UK: /ˈskɛptɪk(ə)l/ | US: /ˈskɛptɪk(ə)l/
adj. having or expressing doubt about the truth or validity of something
adj. inclined to question or challenge accepted opinions
The word sceptical traces back to the Greek skeptikos, meaning "inquiring" or "reflective." It originally described philosophers who questioned dogmatic claims. Over time, the term evolved to emphasize doubt or hesitation, particularly in English, where it gained the spelling sceptical (or skeptical in American English). The morphemes reflect a logical progression from "observation" to "doubtful attitude," capturing the essence of critical scrutiny.
