Sign of quality of team operation in the Church of Scotland
I believe the answer is:
kitemark
'sign of quality' is the definition.
The definition suggests a singular noun which matches the answer.
'team operation in the church of scotland' is the wordplay.
I cannot quite see how this works, but
an anagram of 'team' is 'tema' which is present in the answer.
'church' could be 'kirk' (kirk is a kind of church) and 'kirk' is found within the leftover letters.
This accounts for all the letters.
This may be the basis of clue (or it may be nonsense).
'of' acts as a link.
Can you help me to learn more?
(Other definitions for kitemark that I've seen before include "British Standards Institution's symbol of approval" , "British Standards Institution stamp of quality" .)
