English married couple have a cuddle (7)
I believe the answer is:
embrace
'a cuddle' is the definition.
(I know that cuddle is a more specific form of the action embrace)
'english married couple' is the wordplay.
'english' becomes 'E' (abbreviation).
'married' becomes 'm' (abbreviation, e.g. in genealogy).
'couple' becomes 'brace' (brace can mean a pair of something).
'e'+'m'+'brace'='EMBRACE'
'have' acts as a link.
(Other definitions for embrace that I've seen before include "Hug, put arms around" , "Hug; adopt" , "Willingly accept" , "Hold closely, include" , "Hold affectionately" .)
