Come round the island to the north (5)
I believe the answer is:
waken
'come round' is the definition.
(I've seen this before)
'island to the north' is the wordplay.
'island' becomes 'wake' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'to the north' becomes 'N' (abbreviation).
'wake'+'n'='WAKEN'
'the' is the link.
Can you help me to learn more?
(Other definitions for waken that I've seen before include "Arouse from sleep" , "Stir yourself" , "Rouse from sleep" , "Come round" .)
