Alarm seeing daughter study (5)
I believe the answer is:
dread
'alarm' is the definition.
(I've seen this before)
'daughter study' is the wordplay.
'daughter' becomes 'd' (genealogical abbreviation).
'study' becomes 'read' (synonyms).
'd'+'read'='DREAD'
'seeing' is the link.
(Other definitions for dread that I've seen before include "Dared to fear greatly" , "Be very averse to" , "Terrible fear" , "Fear - dire" , "Anticipate fearfully" .)
