Smoker's accessory easier to carry? (7)
I believe the answer is:
lighter
I believe this clue is a double definition.
'smoker's accessory' is the first definition.
(a cigarette lighter)
'easier to carry?' is the second definition.
(Other definitions for lighter that I've seen before include "that leads the way for others?" , "Substitute for match" , "craft" , "Boat with a flat bottom for carrying heavy loads" , "Tender, launch" .)
