Some top-end or second-class support? (7)
I believe the answer is:
endorse
'support?' is the definition.
(I know that support can be written as endorse)
'some top-end or second-class' is the wordplay.
I cannot really understand how this works, but
'or' is found in the answer.
'second' could be 's' (common abbreviation) and 's' is found in the answer.
an anagram of 'end' is 'nde' which is present in the left over letters.
A single letter 'e' remains 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 endorse that I've seen before include "Give public approval of (something)" , "Give backing to" , "Countersign" , "Docket" , "Put one's name to, approve" .)
