See daughter's worried (4)
I believe the answer is:
date
'see' is the definition.
('date' can be a synonym of 'see')
'daughter's worried' is the wordplay.
'daughter' becomes 'd'.
'worried' becomes 'ate' (I've seen this before).
'd'+'ate'='DATE'
(Other definitions for date that I've seen before include "escort" , "See 12" , "Fruit with stone" , "Sweet edible fruit" , "retrieved from palmtop?" .)
