Dictionary entry that's clearer when higher (10)

Ross

I believe the answer is:

definition

I believe this is a double definition.

'dictionary entry' is the first definition.
(a dictionary definition)

'that's clearer when higher' is the second definition.
(as in high definition television)

(Another definition for definition that I've seen is " (Word's) meaning".)

I've seen this clue in The Guardian.
