Include in a show of affection (7)
I believe the answer is:
embrace
I believe this clue is a double definition.
'include' is the first definition.
(embracing is a kind of including)
'a show of affection' is the second definition.
(I've seen this in another clue)
'in' acts as a link.
(Other definitions for embrace that I've seen before include "Include - hug" , "Enfold in arms, hug" , "bear-hug?" , "Enfold affectionately in arms" , "affectionate greeting" .)
