c - Why does ENOENT mean "No such file or directory"?

What does the ENT mean in ENOENT?

Shouldn't the error:

No such file or directory

just be named by ENOFILE?

Is there any story or reason?

It's an abbreviation of Error NO ENTry (or Error NO ENTity), and can actually be used for more than files/directories.

It's abbreviated because C compilers at the dawn of time didn't support more than 8 characters in symbols.
