Hills, wild and rugged in the Trossachs (4)
I believe the answer is:
tors
'hills' is the definition.
(tor is a kind of hill)
'wild and rugged in the trossachs' is the wordplay.
I cannot quite understand how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found in the answer.
The remaining letters 'ors' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for tors that I've seen is " High rocky hills".)
