Roamed dry ground — riding this? (9)
I believe the answer is:
dromedary
'riding this?' is the definition.
The definition suggests a singular noun which matches the answer.
'roamed dry ground' is the wordplay.
'ground' indicates an anagram ('grind' the letters into a new form).
'roamed'+'dry'='roameddry'
'roameddry' anagrammed gives 'DROMEDARY'.
Can you help me to learn more?
(Other definitions for dromedary that I've seen before include "Arab racer" , "Creature" , "One-humped camel bred for riding" , "Animal" , "Arabian camel with one hump" .)
