Awesome daughter to study (5)
I believe the answer is:
dread
'awesome' is the definition.
(I've seen this in another clue)
'daughter to study' is the wordplay.
'daughter' becomes 'd' (genealogical abbreviation).
'to study' becomes 'read' ('read' can be a synonym of 'study').
'd'+'read'='DREAD'
(Other definitions for dread that I've seen before include "alarm" , "Great fear or apprehension" , "Adder (anag)" , "Terror" , "Apprehensive fear" .)
