Possess the right bags; they’re for bushcraft (10)
I believe the answer is:
haversacks
'for bushcraft' is the definition.
Although both the answer and 'bushcraft' are nouns, they are not in the same form of the noun.
'possess the right bags' is the wordplay.
'possess' becomes 'have' (synonyms).
'the right' becomes 'r' (common abbreviation).
'bags' becomes 'sacks' (sack is a kind of bag).
'have'+'r'+'sacks'='HAVERSACKS'
'they're' is the link.
Can you help me to learn more?
(Other definitions for haversacks that I've seen before include "having these on their backs" , "bags" .)
