Short match (5)
I believe the answer is:
light
I believe this clue is a double definition.
'short' is the first definition.
('light' can be similar in meaning to 'short')
'match' is the second definition.
(thesaurus)
(Other definitions for light that I've seen before include "Easy to carry" , "Source of illumination" , "Illumination weights little" , "Illumination - not serious!" , "Not too demanding" .)
