In sport, it may well be a little bit off course (5)
I believe the answer is:
divot
'off course' is the definition.
The answer and definition can be both natural objects as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'in sport it may well be a little bit' is the wordplay.
I cannot really understand how this works, but
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is located in the answer.
'bit' could be 'o' (resembles 0, a binary digit or bit) and 'o' is present in the answer.
The remaining letters 'div' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for divot that I've seen before include "Turf lifted by golf club" , "Sod" , "Piece of turf dug out of a lawn" , "Clump of turf for a golfer to replace" , "Displaced grass" .)
