Song of Malaya (3)
I believe the answer is:
lay
'song' is the definition.
(lay is a kind of song)
'of malaya' is the wordplay.
'of' indicates a hidden word.
'LAY' is hidden in the letters of 'malaya'.
(Other definitions for lay that I've seen before include "Air" , "Set down; song" , "Unprofessional" , "Not clerical or professionally qualified" , "Non-clerical, amateur" .)
