Go over bit of ground to see grump (10)
I believe the answer is:
crosspatch
'grump' is the definition.
(synonyms)
'go over bit of ground to see' is the wordplay.
'go over bit of ground' becomes 'patch' (I can't explain this - if you can you should believe this answer much more).
'to' means one lot of letters go next to another (I've seen this in other clues).
'see' becomes 'cross' (crossing is a kind of seeing).
'patch' put after 'cross' is 'CROSSPATCH'.
Can you help me to learn more?
(Other definitions for crosspatch that I've seen before include "Irascible type" , "Churl" , "Grumpy type" , "bad-tempered type" , "Ill-natured person" .)
