Which word is defined as 'silent, not talkative'?

• A. Tacit
• B. Taciturn
• C. Tirade
• D. Vex

Answer: (B)

Describing someone as silent and not talkative points to a person who tends to say little. The word that fits this sense directly is taciturn, meaning habitually quiet or uncommunicative. It captures a temperament or habitual behavior of not speaking much.

Tacit, while related to silence, means understood or implied without being stated, or unspoken approval; it’s more about what is not said or assumed rather than a person’s tendency to speak little. The remaining options don’t fit the sense here: a tirade is a long, angry speech, which is the opposite of being silent, and vex means to irritate or annoy.
