Sense: adjective/1
All four words describe mental quickness, but they differ in register, scope, and typical contexts. 'Clever' (A1) is the most general and neutral — it can describe a child solving a puzzle or an animal learning a trick. 'Intelligent' is more formal and often suggests a deep, analytical ability; you would call a scientist 'intelligent' rather than 'clever' in a formal paper. 'Smart' is common in American English and emphasises practical, street-wise judgement — a 'smart business decision' is about good sense, not just IQ. 'Bright' is informal and warm, used especially for children who learn fast, with a positive, encouraging tone ('What a bright little girl!'). 'Quick-witted' specifically means someone can think and respond very fast in conversation, often with humour. For a classroom setting, 'clever student' and 'bright student' are natural; 'intelligent student' sounds more serious; 'quick-witted student' emphasises fast verbal responses rather than overall ability.

Etymology
The origin of 'clever' is not completely certain. It first appeared in Middle English (1300s) as 'cliver', meaning 'quick, expert' or 'handy'. Many linguists believe it came from Old Norse 'klókr', meaning 'cunning, shrewd'. The sense of physical skill ('clever with her hands') is the older meaning; the mental quickness sense ('a clever student') developed later. Over time the word expanded to describe not just people but also well-designed objects and ideas. The disapproving sense (a 'clever remark' that is witty but rude) appeared in the 1700s.
