End of log turned over in a small wood (5)
I believe the answer is:
grove
'a small wood' is the definition.
(I've seen this in another clue)
'end of log turned over' is the wordplay.
'end of' suggests the final letters.
'turned' indicates an anagram.
The last letter of 'log' is 'g'.
'over' anagrammed gives 'rove'.
'g'+'rove'='GROVE'
'in' acts as a link.
(Other definitions for grove that I've seen before include "Dictionary-maker" , "Group of trees or a small wood" , "Writer on music" , "Small wood or avenue of trees" , "Small woodland" .)
