Brusque, in daughter's estimation (5)
I believe the answer is:
terse
'brusque' is the definition.
(thesaurus)
'in daughter's estimation' is the wordplay.
'in' indicates the answer is hidden within the clue.
'TERSE' can be found hidden inside 'daughters estimation'.
(Other definitions for terse that I've seen before include "Reset to be pithy" , "Abrupt, concise" , "Compact" , "Short and to the point" , "Pithy and concise" .)
