Packing it with trouble makes you smile a lot? (6)
I believe the answer is:
kitbag
'lot?' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I don't see?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for kitbag that I've seen before include "Serviceman's canvas pack" , "knapsack" , "Cylindrical canvas holder for soldiers' clothes" .)
