Captivate neighbours at table with song (7)
I believe the answer is:
enchant
'captivate neighbours' is the definition.
'enchant' can be an answer for 'captivate' (synonyms). I'm not certain of the 'neighbours' bit.
'at table with song' is the wordplay.
'at table' becomes 'en' (I can't justify this - if you can you should give a lot more credence to this answer).
'with' says to put letters next to each other.
'song' becomes 'chant' (song sung by a crowd).
'en'+'chant'='ENCHANT'
Can you help me to learn more?
(Other definitions for enchant that I've seen before include "Appeal" , "transport" , "Delight, cast spell over" , "Fascinate - delight" , "Bewitch, charm" .)
