1. The Truth Will Out
“The truth will out” means hidden facts always come to light in the end.
Word by Word Meaning
“Truth” is that thing which is real. “Will” points to the future. “Out” means into the open. The grammar is old. Today we would say “will come out.”
Idiomatic Meaning
This expression says that secrets can not stay buried forever. Someone may hide a fact, but people will find it later.
Origin note: Shakespeare wrote a line very close to it in The Merchant of Venice. Whether he invented the phrase is not confirmed.
Examples
- He hid the mistake for months, but the truth will out.
- “Do not lie to your teacher,” Mom said. “The truth will out.”
2. Gospel Truth
“Gospel truth” means something that is completely and surely true.
Word-by-Word Meaning
“Gospel” comes from an Old English word for “good news.” “Truth” is what is real.
Idiomatic Meaning
The phrase describes a statement so true that nobody should doubt it. People also use it in a light way, as in “Do not take it as gospel.”
Origin note: Dictionaries trace the idiom to the 1600s, when it pointed to truths from the Bible. By the late 1800s, people used it for any strong truth.
Examples
- My grandfather’s stories were not always gospel truth, but they were fun.
- The manager said the sales numbers were gospel truth, so nobody checked them.
3. Economical With the Truth
“Economical with the truth” means telling only part of the facts so people get a false picture.
Word-by-Word Meaning
“Economical” means careful with spending. Here, the speaker spends the truth like money and uses as little as possible.
Idiomatic Meaning
It is a polite way to say someone is not fully honest. The speaker avoids a direct lie but still misleads.
Origin note: The modern use is often linked to Sir Robert Armstrong, a British official, after a 1986 trial. Edmund Burke wrote about an “economy of truth” much earlier, but he meant it as a careful, kind habit. The modern idiom is negative.
