The constinit specifier shall be applied only to a declaration of a variable with static or thread storage duration.

- [dcl.constinit] p1

This is broken wording because [basic.pre] says:

A variable is introduced by the declaration of a reference other than a non-static data member or of an object.
The variable's name, if any, denotes the reference or object.

What the former paragraph says is thus:

The constinit specifier shall be applied only to a declaration of a declaration of an object or reference other than a non-static data member or of an object, with static or thread storage duration.

Inlining the definition gives us "declaration of a declaration" which is either meaningless or recursive.

Suggested Fix

Extend [basic.pre] p6 as follows:

 A *variable* is introduced by the declaration of a reference
 other than a non-static data member or of an object.
 The variable's name, if any, denotes the reference or object.
+Such a declaration is called *variable declaration*.

Then, in the entire document:

-declaration of a variable
+variable declaration
