Heard why I rested in bunk like some children (6)
I believe the answer is:
boyish
'heard why i rested in bunk like some children' is the definition.
I can't tell whether this defines the answer.
'heard why i rested in bunk like' is the wordplay.
'heard why i rested in bunk' becomes 'boy' (I am not sure about this - if you are sure you should believe this answer much more).
'like' becomes 'ish' (similar in meaning).
'boy'+'ish'='BOYISH'
Can you help me to learn more?
(Other definitions for boyish that I've seen before include "Youthful" , "like a young man" , "how immature youth is" , "Like a young lad" , "Juvenile" .)
