Coverage for building (not this church) (6)
I believe the answer is:
thatch
'coverage for building not this church' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'not this church' is the wordplay.
'not this' becomes 'that' (that one as opposed to this one).
'church' becomes 'ch' (common abbreviation).
'that'+'ch'='THATCH'
Can you help me to learn more?
(Other definitions for thatch that I've seen before include "unusual roof" , "An old-fashioned roof covering of straw, reeds etc" , "Old-fashioned roof covering material" , "Cover for house" , "Old roof covering for house" .)
