Daughter in bar with Italian robber (6)
I believe the answer is:
bandit
'robber' is the definition.
(bandit is a type of robber)
'daughter in bar with italian' is the wordplay.
'daughter' becomes 'd' (genealogical abbreviation).
'in' is an insertion indicator.
'bar' becomes 'ban' (I've seen this before).
'with' says to put letters next to each other.
'italian' becomes 'it' (abbreviation for Italian).
'ban'+'it'='banit'
'd' put inside 'banit' is 'BANDIT'.
(Other definitions for bandit that I've seen before include "Enemy aircraft" , "Outlaw, robber" , "Member of a gang of robbers" , "Violent outlaw" , "Dan bit the robber badly" .)
