"Leave No Stone Unturned" – Meaning

The phrase "leave no stone unturned" implies "making all possible efforts to achieve or get something done". Generally speaking, the phrase denotes "using every possible option or exhausting every available resource when attempting to solve a problem or completing a task". It signifies "doing things conscientiously and comprehensively without missing a step".

The saying is typically used in contexts where there's some kind of "searching" involved. But then you can use the phrase in situations that don't entail "hunting for things". "Leaving a stone unturned" would imply "not looking in an area where the missing thing might be" or "failing to try a particular method to complete a task."

The basic premise behind the saying is if you were to look for a thing in an area filled with stones, you would likely turn over or dislodge each piece of rock to check if the lost object is lurking somewhere underneath. The "search" carried out is usually within a particular location's boundaries. It could entail moving abstract things or physical objects.

When the phrase is used in the "finding things" context, it essentially means "look everywhere". When used in the "problem-solving" or "task completion" situation, the expression denotes "try everything".

Proverbs or phrases similar to or synonymous with "leave no stone unturned" include:

  • go all out

  • push the envelope's edge
  • spare no effort/expense
  • move mountains
  • look high and low, etc.

The phrases mentioned above may or may not be proverbs or recognized expressions, but they mean identical or something similar to "leave no stone unturned".

The Origin of the Phrase

There's no proper documented evidence stating the origin of the expression. But there are quite a few legends, which may or may not be accurate.

According to Greek mythology, Apollo Pythios, a Greek god, and the oracle of Delphi then, uttered those words to Polycrates. It was when Polycrates was trying to unearth treasure buried in a land that he had bought after hearing rumors of wealth being hidden by Mardonius, a Persian military commander.

When Polycrates initially couldn't find the supposedly hidden treasure, he consulted Apollo for advice, who said "leave no stone unturned" in response. Paying heed to the advice, Polycrates started to look for things hidden behind or under every rock literally. And as he kept doing that, he happened to find a massive hoard of gold.

Others believe the phrase has nothing to do with the "Apollo story" and that the metaphor has its roots in the activity wherein people hunt for crabs alongside the seashore. This origin tale seems plausible as crabs generally lie hidden beneath rocks that people move when looking for the decapod variety.

In the Heraclids or Heracleidae, it's believed Euripides, the tragedian from ancient Greece, used the phrase to mean "leave nothing undone". He was perhaps just recounting the Greek legend mentioned above.

Using the Phrase "Leave No Stone Unturned" in Texts

As mentioned above, "leave no stone unturned" denotes a "search". The proverb is commonly used in texts or speech to praise or highlight someone's diligent work or to guarantee a thorough search, as a result.
