One replaced by bishop in a 1760-yard walk (5)
I believe the answer is:
amble
'walk' is the definition.
(amble is a kind of walk)
'one replaced by bishop in a 1760-yard' is the wordplay.
I cannot quite see how this works, but
'one' could be 'a' (a thing is one thing) and 'a' is present in the answer.
'bishop' could be 'b' (chess abbreviation) and 'b' is present in the answer.
'yard' could be 'm' (synonyms) and 'm' 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 amble that I've seen before include "Wander casually" , "Blame for slow walk" , "Walk in a leisurely fashion" , "Move at an easy pace" , "Meander" .)
