Asian to look for, by the sound of it (4)
I believe the answer is:
sikh
'asian' is the definition.
(Sikh is an example)
'look for by the sound of it' is the wordplay.
'look for' becomes 'seek' ('seek' can be a synonym of 'look for').
'by the sound of it' indicates a 'sounds like' (homophone) clue.
'seek' is a homophone of 'SIKH'.
'to' acts as a link.
(Other definitions for sikh that I've seen before include "Religious adherent (eastern)" , "Member of a Hindu religion" , "Guru's disciple" , "Member of Indian religious sect, wears turban" , "Indian believer" .)
