Gear case? (6)
I believe the answer is:
kitbag
'gear case?' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'gear case?' is the wordplay.
'gear' becomes 'kit' (kit is a kind of gear).
'case?' becomes 'bag' (bag is a kind of case).
'kit'+'bag'='KITBAG'
Can you help me to learn more?
(Other definitions for kitbag that I've seen before include "Serviceman's canvas pack" , "Cylindrical canvas holder for soldiers' clothes" , "knapsack" .)
