What Does “Not Telling the Truth” Mean?

“Not telling the truth” means failing to say what is actually true. It covers a wide range: from a small white lie told to spare someone’s feelings, to a serious falsehood meant to deceive. The phrase is softer than the word “lying,” which is one reason people reach for it — it sounds less like an accusation.

For example: “He was not telling the truth about where he went last night.” Or: “The report was not telling the truth about the company’s profits.” In both cases, the truth is either hidden, twisted, or replaced with something false.

How to Use “Not Telling the Truth” Correctly

The phrase is a negative construction: not + telling the truth. It works as a verb phrase (“He is not telling the truth”) or as a noun phrase describing behavior (“Not telling the truth can ruin trust”). Because it is softer than “lying,” people often choose it when they want to accuse someone without sounding too aggressive.

Be careful with double negatives. “He is not not telling the truth” is confusing — say “He is telling the truth” instead. Also note that “not telling the truth” and “telling a lie” are not always identical: staying silent about the truth is “not telling the truth,” but it is not always a lie in the strict sense.

When Not to Use a Synonym for “Not Telling the Truth”

Mistake 1: Calling an honest error “lying.”
Wrong: “The teacher was lying about the exam date.”
Corrected: “The teacher was mistaken about the exam date.”
A lie requires intent — a simple mistake is not dishonesty.

Mistake 2: Using “fibbing” for serious fraud.
Wrong: “The company was just fibbing on its tax returns.”
Corrected: “The company was committing fraud on its tax returns.”
“Fibbing” sounds playful and is completely wrong for serious offenses.

Mistake 3: Using “deceptive” when you mean “unclear.”
Wrong: “The instructions were deceptive.”
Corrected: “The instructions were unclear.”
“Deceptive” implies intent to mislead; “unclear” just means badly written.

Frequently Asked Questions

What is a softer way to say someone is not telling the truth?
Try “being economical with the truth,” “stretching the truth,” or “not being entirely honest.” These phrases soften the accusation.

Is “misleading” the same as “lying”?
Not exactly. Lying means stating something false on purpose. Misleading can mean giving a wrong impression even with technically true words — for example, quoting a statistic out of context.

What is a single word for “not telling the whole truth”?
“Concealing” and “withholding” both work. In legal settings, “misrepresentation” covers statements that leave out key facts.

What is the formal word for lying in court?
Perjury — lying under oath. It is a crime, so it is far stronger than “not telling the truth.”
