Ground dry enough for racer (9)
I believe the answer is:
greyhound
'racer' is the definition.
(I've seen this before)
'ground dry enough' is the wordplay.
'ground' is an anagram indicator ('grind' the letters into a new form).
'dry'+'enough'='dryenough'
'dryenough' anagrammed gives 'GREYHOUND'.
'for' acts as a link.
(Other definitions for greyhound that I've seen before include "Fast-moving dog" , "Tall, slender canine" , "Want to bet on it?" , "racer" , "slender runner?" .)
