Wolves defended by supporter, one with a big bag (10)
I believe the answer is:
backpacker
'one with a big bag' is the definition.
I can't tell whether this defines the answer.
'wolves defended by supporter' is the wordplay.
'wolves' becomes 'pack' (pack of wolves).
'defended by' indicates putting letters inside.
'supporter' becomes 'backer' (backer is a kind of supporter).
'pack' put inside 'backer' is 'BACKPACKER'.
Can you help me to learn more?
(Other definitions for backpacker that I've seen before include "Sort of traveller" , "Traveller with a rucksack" , "Hiker" , "One travelling with a rucksack" , "Traveller with little luggage" .)
