Works in pub with odd people out of clubs (7)
I believe the answer is:
innards
'works' is the definition.
(I've seen this before)
'pub with odd people out of clubs' is the wordplay.
'pub' becomes 'inn' (I've seen this before).
'with' says to put letters next to each other.
'odd people' becomes 'cards' (I've seen this before).
'out of' is a deletion indicator.
'clubs' becomes 'c' (abbreviation used in card games such as bridge).
'cards' with 'c' taken away is 'ards'.
'inn'+'ards'='INNARDS'
'in' is the link.
(Other definitions for innards that I've seen before include "Informal intestines and organs" , "Informally, stomach and bowels" , "Guts of mechanism" , "Informally, the stomach and entrails" , "Insides" .)
