raring

I'm a little stuck... Click here to teach me more about this clue!

'enthusiastic' is the definition.
(as in 'raring to go')

I don't understand how the remainder of the clue works.

(Other definitions for raring that I've seen before include "Agog" , "Very keen (to go?)" , "Eager, impatient" , "Very eager (to do something)" , "Eager (to go?)" .)

I've seen this clue in The Times.
