Is it easier to carry than matches? (7)
I believe the answer is:
lighter
'matches?' is the definition.
(matches is a kind of lighter)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for lighter that I've seen before include "Barge (more likely to float?)" , "More manageable" , "Canal boat with a flat bottom" , "relieved of some cargo?" , "Less weighty" .)
