The first city for capital investment (6)
I believe the answer is:
turban
'capital investment' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'the first city' is the wordplay.
'the first' becomes 't' (1st letter of 'the').
'city' becomes 'urban' (urban means relating to a city).
't'+'urban'='TURBAN'
'for' is the link.
Can you help me to learn more?
(Other definitions for turban that I've seen before include "Wound headgear" , "Head-dress of male Muslim and Sikh" , "Sikh headdress of scarf wound around head" , "Sikh headgear" , "A Sikh's headdress" .)
