Boy standing over soldier covered in powder, sentimental (9)
I believe the answer is:
nostalgic
'sentimental' is the definition.
(thesaurus)
'boy standing over soldier covered in powder' is the wordplay.
I cannot really understand how this works, but
'boy' could be 'al' and 'al' is present in the answer.
'over' could be 'o' (cricket abbreviation) and 'o' is located in the answer.
'soldier' could be 'gi' (government issue or general issue) and 'gi' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for nostalgic that I've seen before include "Home sick" , "Wistful" , "Longing for familiar things or persons" , "Sentimental about the past" , "longing for home" .)
