Party line repeated for Ken or Barbie? (4)
I believe the answer is:
doll
'ken or barbie?' is the definition.
(I've seen this in another clue)
'party line repeated' is the wordplay.
'party' becomes 'do' (do is a kind of party).
'line' becomes 'l' (used when specifying particular lines from a poem).
'repeated' says to double the letters.
'l' duplicated is 'll'.
'do'+'ll'='DOLL'
'for' acts as a link.
(Other definitions for doll that I've seen before include "A girl's plaything" , "Puppet" , "Toy replica of a person" , "Child's toy figure" , "Toy baby" .)
