Indigo from Manila (4)
I believe the answer is:
anil
'indigo' is the definition.
(anil is another word for indigo)
'from manila' is the wordplay.
'from' says the answer is hidden in the clue.
'ANIL' is hidden in the letters of 'manila'.
(Other definitions for anil that I've seen before include "Shrub providing indigo" , "West Indian shrub, source of indigo" , "Indian man" , "Indigo (plant or dye)" , "Colouring" .)
