Filipinos essentially packing trunks (5)
I believe the answer is:
noses
'trunks' is the definition.
(an elephant's trunk is its nose)
'filipinos essentially packing' is the wordplay.
'packing' indicates a hidden word.
'NOSES' is hidden in the letters of 'filipinos essentially'.
(Other definitions for noses that I've seen before include "Proboscises" , "Facial features" , "Examines or detects by smelling" , "Hooters" , "Snouts" .)
