What soldiers may do to keep decently warm? (5)
I believe the answer is:
dress
'warm?' is the definition.
Both the answer and definition are adjectives. Maybe there's an association between them I don't understand?
'what soldiers may do to keep decently' is the wordplay.
I cannot really understand how this works, but
'soldiers' could be 're' (Royal Engineers) and 're' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for dress that I've seen before include "formal attire" , "Decorate; garment" , "Put on one's clothes" , "Frock" , "For display, arrange" .)
