Daughter sick of flavouring (4)
I believe the answer is:
dill
'flavouring' is the definition.
(dill is a kind of flavouring)
'daughter sick' is the wordplay.
'daughter' becomes 'd' (genealogical abbreviation).
'sick' becomes 'ill' (synonyms).
'd'+'ill'='DILL'
'of' is the link.
(Other definitions for dill that I've seen before include "medicinal plant" , "Fool" , "Pickle flavouring" , "Plant of the celery family; leaf is a herb, seeds a spice" , "Culinary herb" .)
