mettre son doigt sur la plaie

Meaning: Identifying the exact problem or sensitive issue in a situation.

Language: French

Literally: to put one's finger on the wound

Category: Body & Senses

Origin: Often traced, too quickly, to doubting Thomas putting his finger into Christ's wounds — but that scene is about verifying a wound already known and shown, not about locating a hidden one, which is the entire point of the French idiom. The better fit is a doctor's exam: pressing along an area of complaint until a finger lands on the exact spot that makes the patient wince, which is precisely how the phrase is used — naming, unerringly, the one detail in a situation that actually hurts. Plaie comes from Latin plaga, a blow or a wound, and doigt from digitus by way of Old French ditus.
