What does closemouthed mean?
"Closemouthed" describes a person who is reluctant to speak freely, share information, or reveal what they know — someone whose lips are figuratively sealed. It is an adjective formed from "close" (in the sense of shut) plus "mouth," and it typically implies deliberate discretion rather than mere shyness: a closemouthed executive may answer questions politely while giving away nothing of substance. In everyday usage the word most often appears in phrases such as "closemouthed about his plans" or "remained closemouthed throughout the interview." Its connotation ranges from admiring (suggesting trustworthiness and the ability to keep secrets) to mildly critical (suggesting evasiveness or withholding). Synonyms include "reticent," "tight-lipped," and "taciturn," though each carries its own shade of meaning. The word is standard in both British and American English and suits formal writing especially well.
adjectiveReluctant to reveal information or express one's thoughts; habitually secretive or reserved in speech.
- Disinclined to reveal information, secrets, or one's own opinions; habitually silent or evasive in speech.
"Even under sustained questioning, the senator remained closemouthed about the details of the negotiation."
"The firm's lawyers were closemouthed about which client had requested the audit."
"A closemouthed man by nature, he let others do the talking at every family gathering."
The "close" in "closemouthed" isn't about proximity — it's the same Latin root that gives us "cloister" and "recluse," literally shutting a door on your words.

Etymology of closemouthed
"Closemouthed" is a straightforward English compound of "close" and "mouth," modeled on older formations like "closefisted" and later paralleled by "close-lipped." The element "close" derives from Latin "clausus," the past participle of "claudere" (to shut), which also yields English words such as "cloister," "clause," "recluse," and "seclude." The compound emerged in English in the early modern period as writers sought vivid terms for secrecy and reticence.
