Exercise before sangrias on vacation is noble (7)
I believe the answer is:
peeress
'is noble' is the definition.
(I've seen this in another clue)
'exercise before sangrias on vacation' is the wordplay.
'exercise' becomes 'pe' (Physical Education).
'before' becomes 'ere' (poetic term for 'before').
'on vacation' says to hollow out the word (remove centre letters).
'sangrias' with its centre removed is 'ss'.
'pe'+'ere'+'ss'='PEERESS'
(Other definitions for peeress that I've seen before include "Noblewoman" , "Female House of Lords member" , "Lady" , "Woman from other place" , "Female noble" .)
