Higher class work performed by tree surgeon? (1,3,5)
I believe the answer is:
a cut above
'higher' is the definition.
(thesaurus)
'class work performed by tree surgeon?' is the wordplay.
I cannot really understand how this works, but
'tree' could be 'bo' (bo tree is a kind of tree) and 'bo' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for a cut above that I've seen before include "Noticeably superior to" , "Something superior" .)
