Place to dance in a girl's company (5)
I believe the answer is:
disco
'place to dance' is the definition.
(I've seen this in another clue)
'girl's company' is the wordplay.
'girl's' becomes 'Dis' (Di is short for Diana).
'company' becomes 'co' (abbreviation).
'dis'+'co'='DISCO'
'in a' is the link.
(Other definitions for disco that I've seen before include "Discotheque (abbrev.)" , "Nightclub with recorded music, in short" , "Youngsters' dance venue" , "Modern dancehall of youth" , "Public dance hall with recorded music" .)
