As far as a cowboy can ride? (5)
I believe the answer is:
range
'can ride?' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'as far as a cowboy' is the wordplay.
I cannot really understand how this works, but
'a' could be 'an' and 'an' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for range that I've seen before include "Extent; line of mountains" , "Wander freely" , "Large, grassy land for livestock in the US" , "Mountain stretch" , "Number of items in a series" .)
