Distance a cowboy can ride? (5)
I believe the answer is:
range
'distance' is the definition.
(I've seen this in another clue)
'a cowboy can ride?' is the wordplay.
I cannot really understand how this works, but
'a' could be 'an' and 'an' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for range that I've seen before include "Take sides" , "practise shooting here" , "area for stock" , "Extent - shooting area" , "Stove; variety" .)
