常見錯誤
What are common mistakes with "Expression"?Which "Expression" sentences look correct but are wrong?
×He used a very good expression to describe the situation.
✓He used a very good expression to describe the situation.
This is grammatically correct but often misused. Learners confuse 'expression' with 'word' or 'phrase'. The sentence is not wrong, but the intended meaning might be better served by 'word', 'phrase', or 'idiom' depending on context. 'Expression' is more general and can refer to a single word, a phrase, or even a facial expression.
×I learned a new English expression: 'computer'.
✓I learned a new English word: 'computer'.
'Expression' is too broad for a single, simple vocabulary word. Use 'word' for individual lexical items. 'Expression' is better suited for phrases, idioms, or common sayings that convey a specific idea.
×His expression was that he was tired.
✓He expressed that he was tired. / His expression showed he was tired.
Confusion between the noun 'expression' and the verb 'express'. The noun 'expression' refers to the thing that is communicated (the look, the phrase), not the act of communicating. You cannot say 'his expression was that...'. Use the verb 'express' for the action, or rephrase using 'show' or 'indicate' with the noun.
×Please write down the mathematical expression: 5 > 3.
✓Please write down the mathematical expression: 5 > 3.
This is technically correct in mathematics. However, learners often overuse 'expression' in non-idiomatic, general contexts where 'phrase', 'sentence', or 'term' would be more natural. In everyday language, 'expression' often implies a fixed or common way of saying something.
×We studied about American expressions in class.
✓We studied American expressions in class.
Unnecessary preposition 'about' after the verb 'study' when the object is the thing being studied directly. Use 'study + something'. Use 'study about' only in very informal contexts, which is generally considered incorrect in standard English.
