Synonym discussion

Sense: adjective/1

All four words describe someone who is not speaking, but they differ in tone and use. 'Silent' is the most general and neutral: it simply means making no sound ('The room fell silent when the headteacher walked in'). 'Quiet' suggests a naturally reserved manner rather than deliberate concealment ('Élise was quiet throughout the dinner'). 'Tight-lipped' specifically describes someone who refuses to share information, often in a formal context ('The minister remained tight-lipped about the budget cuts'). 'Secretive' carries a more negative connotation of actively hiding things ('Ziad was secretive about his weekend plans'). 'Keep mum' is informal and British, used for keeping a surprise or secret by choice, without the suspicion that 'secretive' implies. For example, you would keep mum about a birthday gift but stay tight-lipped about a company's financial trouble.

Etymology

Middle EnglishEnglish

The noun sense 'mother' comes from a shortening of 'mother', first recorded in informal British English around the early 19th century. The noun sense 'chrysanthemum' is also a shortening, appearing in the late 19th century among gardeners and florists. The adjective sense traces back to Middle English 'mum' (meaning 'silent'), which imitates the sound made when the lips are pressed together — a natural gesture for silence.
