Hit the Nail on the Head
“Hit the nail on the head” means to identify something exactly or describe the central cause accurately. The expression is centuries old, but the engine separates an ambiguous c.1438 precursor from a clearer 1559 use rather than claiming a single proven invention point.
It means to be exactly right or identify the key point. Phrase-history research reports a nail-on-the-head wording in The Book of Margery Kempe around 1438, though that passage’s sense is debated, and a much clearer 1559 use in William Cuningham’s The Cosmographical Glass. The exact origin or coiner is not established.
Key details
What the evidence supports
The c.1438 Margery Kempe wording proves the modern idiom was already being used in exactly its current sense.
The wording is historically important, but the sense of that passage is debated; the engine records it as a related early form.
William Cuningham coined the expression in 1559.
The 1559 wording reportedly says “as the saying is,” which points to an expression already in circulation rather than proving coinage by Cuningham.

Clearer 1559 Use
The same specialist source reports William Cuningham’s 1559 The Cosmographical Glass using “You hit the naile on the head (as the saying is),” which is clearer evidence that the expression was already proverbial.
Early Wording
Phrase Finder reports a c.1438 passage in The Book of Margery Kempe containing a “smite the nail on the head” wording. Because the historical sense is not fully clear, the engine treats this as an early related form rather than automatic proof of the modern idiom.
Meaning
Cambridge defines the idiom as describing exactly what is causing a situation or problem, and its American entry also gives the broader sense of being exactly right.
Origin boundary
Neither occurrence proves who coined the phrase. The public record therefore distinguishes documented chronology from invention.
