Filipino native has some time left over (5)
I believe the answer is:
elemi
'filipino native' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'some time left over' is the wordplay.
'some' says the answer is hidden in the clue (some parts of the word are used).
'over' says the letters should be written in reverse.
'imele' is hidden within 'time left'.
'imele' in reverse letter order is 'ELEMI'.
'has' is the link.
Can you help me to learn more?
(Other definitions for elemi that I've seen before include "Oleoresin" , "Tree resin; ie, elm (anag.)" , "It's fragrance" , "Resinous stuff" , "Extract" .)
