Would gear for hiker put money on 52 cards? (8)
I believe the answer is:
backpack
'would gear for hiker put money' is the definition.
I can't tell whether this defines the answer.
'on 52 cards?' is the wordplay.
'on' says to put letters next to each other.
'5a' becomes 'back' (I am not sure about this - if you are sure you should believe this answer much more).
'cards?' becomes 'pack'.
'back' put next to 'pack' is 'BACKPACK'.
Can you help me to learn more?
(Other definitions for backpack that I've seen before include "luggage" , "Hike" , "Knapsack" , "storage space?" , "It carries stuff" .)
