English northern couple with energy to twist (7)
I believe the answer is:
entwine
'twist' is the definition.
(entwining is a kind of twisting)
'english northern couple with energy' is the wordplay.
'english' becomes 'E' (abbreviation).
'northern' becomes 'n' (abbreviation e.g. N. Ireland).
'couple' becomes 'twin' (synonyms).
'with' says to put letters next to each other.
'energy' becomes 'e' (physics symbol as in E=mcw).
'e'+'n'+'twin'+'e'='ENTWINE'
'to' acts as a link.
(Other definitions for entwine that I've seen before include "knit" , "Weave - interlace" , "Get weaving" , "Wind or twist together" , "Interweave" .)
