not true; false
Not true; not correct when you compare it with real facts.
Mẫu sử dụng:
[statement/claim/belief] is untrue
Lỗi thường gặp:
Learners often use *wrong* instead of *untrue* for statements or facts. *Wrong* is possible but usually sounds more casual or emotional (e.g., "That’s wrong"); *untrue* is more factual or careful, especially in news or formal speech. Another mistake is using *untruth* when they simply mean *untrue*; *untruth* is a noun meaning a lie, while *untrue* is an adjective describing a statement.

Not faithful or loyal to a person or to what you have promised.
Mẫu sử dụng:
[someone] is untrue to [someone/something]
Lỗi thường gặp:
Learners sometimes confuse *untrue* with *fake* or *false* when talking about people. *Untrue* is not used to mean a person is not real; it describes being unfaithful or disloyal (e.g., "untrue to his wife"). For objects like a *fake bag*, you should not say *an untrue bag*.

Từ trái nghĩa
faithful (Direct opposite; stresses staying with one partner or keeping a promise.)
|
loyal (Opposite in the sense of continuing to support a person, group, or belief.)

not straight; mechanically off
Not straight or in the right line, especially when a wheel or similar part moves in a side-to-side way.
Mẫu sử dụng:

Learners rarely use this technical sense; a possible confusion is thinking *untrue* here still means *false*. In this context, it is about shape and movement, not about truth or lies.
Từ đồng nghĩa
warped (Similar for objects that are bent or twisted, but less specific to rotating parts.)
|
out of true (Technical phrase meaning not exactly straight or aligned; often used for wheels or frames.)
