Row at a nightclub on the way (7)
I believe the answer is:
discord
'row' is the definition.
(thesaurus)
'a nightclub on the way' is the wordplay.
'a nightclub' becomes 'disco' (I've seen this before).
'on' says to put letters next to each other.
'the way' becomes 'rd'.
'disco'+'rd'='DISCORD'
'at' is the link.
(Other definitions for discord that I've seen before include "Disagreement" , "Opposition" , "Dissension" , "Friction" , "Strife, lack of harmony" .)
