Trust’s foremost in City for capital cover (6)
I believe the answer is:
turban
'capital cover' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'trust's foremost in city' is the wordplay.
'foremost' suggests taking the first letters.
'in city' becomes 'urban' (urban means relating to a city).
The initial letter of 'trusts' is 't'.
't'+'urban'='TURBAN'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for turban that I've seen before include "Piece of cloth worn around the head" , "Headdress worn by Sikh men" , "Nut bar (anag.)" , "Sash wound as head-covering" , "Sikh headdress of scarf wound around head" .)
