Actress Salonga (3)
I believe the answer is:
lea
'actress salonga' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for lea that I've seen before include "''The lowing herd winds slowly o'er the ... '' (Gray)" , "Open pasture" , "pastoral setting" , "authority for teachers" , "Tract of pastureland" .)
