skeptical
UK: ˈskɛptɪkəl | US: ˈskɛptɪkəl
adj. having or expressing doubt about the truth or validity of something
adj. inclined to question or challenge accepted opinions
The word traces back to ancient Greek philosophy, where skeptikos referred to thinkers who critically examined claims rather than accepting them at face value. Over time, the term evolved to emphasize doubt or hesitation, especially in English, where "skeptical" gained its modern meaning of questioning validity or truth. The suffix -ical standardizes it as an adjective, aligning with similar Latinate formations.
