Snow on to higher ground penetrating outskirts of Dundee (4)
I believe the answer is:
dupe
'snow' is the definition.
(thesaurus)
'to higher ground penetrating outskirts of dundee' is the wordplay.
I cannot quite understand how this works, but
'higher' could be 'up' and 'up' is located in the answer.
'outskirts of dundee' could be 'de' (first and last letters of 'Dundee') and 'de' is found in the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'on' is the link.
Can you help me to learn more?
(Other definitions for dupe that I've seen before include "Swindle" , "One deceived, tricked" , "Cat's paw" , "One who is cheated" , "Con" .)
