Rucksack carried by climber, generally (6)
I believe the answer is:
bergen
'rucksack' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'carried by climber generally' is the wordplay.
'carried by' indicates a hidden word.
'BERGEN' is hidden within 'climber generally'.
Can you help me to learn more?
(Other definitions for bergen that I've seen before include "SW Norway port" , "Second city of Norway" , "Norwegian port city" , "Port city of Norway" .)
