Scandinavians, heading to centre in Peak District (5)
I believe the answer is:
andes
'peak district' is the definition.
(I've seen this before)
'scandinavians heading to centre in' is the wordplay.
'scandinavians heading' becomes 'and' (I can't explain this - if you can you should give a lot more credence to this answer).
'to centre' says to take the centre.
'in' becomes 'successful' ('successful' can be similar in meaning to 'in').
The centre of 'successful' is 'es'.
'and'+'es'='ANDES'
Can you help me to learn more?
(Other definitions for andes that I've seen before include "South American mountain chain" , "South American mountains" , "A geographical feature" , "Mounts" , "Peak District" .)
