deader than a doornail

Utterly without life

Deader than a doornail means completely and unmistakably dead, with no possibility of revival.

The phrase emphasizes finality—something is not just dead but conclusively so: The deal is deader than a doornail.

It applies to literal death and to things that have failed utterly: projects, relationships, hopes.

Why doornails should be especially dead is unclear, but the expression has been in use since at least the 14th century.
