In a storm, it could take a bit of climbing (3)
I believe the answer is:
tor
'take a bit of climbing' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'in a storm it' is the wordplay.
'in' indicates the answer is hidden within the clue.
'TOR' can be found hidden inside 'storm it'.
'could' is the link.
Can you help me to learn more?
(Other definitions for tor that I've seen before include "(Dartmoor) rocky hill" , "Rocky prominence" , "Hill or rocky peak" , "Pillar of rock" , "Rocky crag" .)
