Loaded youth spending contents (5)
I believe the answer is:
laden
'loaded' is the definition.
(I know that loaded can be written as laden)
'youth spending contents' is the wordplay.
'youth' becomes 'lad' (lad means a young man).
'spending contents' becomes 'en' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'lad'+'en'='LADEN'
Can you help me to learn more?
(Other definitions for laden that I've seen before include "Like many a cargo ship" , "Encumbered" , "Put on board" , "Like cargo boat" , "Loaded - oppressed" .)
