文法句型

it seems plausible that-clause

a plausible explanation/reason/theory

用法筆記

Frequently modifies abstract nouns like explanation, reason, theory, story, or excuse. Distinguish from sense 2 (adjective/2): this sense judges an idea or argument; sense 2 judges a person's manner. You can call a story plausible without saying anything bad — but calling a person plausible often hints at distrust.

常見錯誤

❌The cake tastes plausible.
✅The cake tastes good.
💡plausible describes ideas or claims, not flavours, looks, or physical qualities.
❌I am plausible that he will come.
✅It is plausible that he will come.
💡use 'it is plausible that…', not a personal subject.

2.形容詞C2
釋義

describes a person, or the way they speak, that comes across as honest and sincere, often as a way to deceive others — for example, a smooth salesman or a clever conman who easily wins your trust.

例句

The conman was so plausible that even my grandmother handed over her savings.

predicative: be so plausible that-clause

Marcus is a plausible liar, which is exactly why nobody on the jury caught him.

collocation: a plausible liar/conman/rogue

同義詞
  • smooth

    informal; same idea of fluent, polished talk that may not be sincere

  • glib

    stronger negative tone; emphasises shallow, ready-made answers

  • specious

    formal; focuses on arguments that look fair but are actually false

反義詞
  • blunt

    describes a speaker who sounds direct and rough, with no smooth charm

  • transparent

    in this contrast, means clearly open and honest — easy to read

文法句型

a plausible liar/salesman/conman

用法筆記

Carries a clearly negative tone — almost always implies the person is hiding something. Subject is usually a person (liar, conman, salesman, politician) or a personal feature (manner, smile, voice). Distinguish from sense 1 (adjective/1): sense 1 judges what is said, sense 2 judges who is saying it. Calling a friend 'plausible' would sound like an accusation.

常見錯誤

❌My new friend is so plausible and kind.
✅My new friend is so charming and kind.
💡calling a person plausible suggests you suspect them of being dishonest.
❌The story sounds plausible because the writer is plausible.
✅The story sounds plausible because the writer is convincing.
💡'plausible writer' implies the writer is a smooth liar, which is rarely the meaning intended.
