Maybe make peeress some genteel bonnets in retirement (7)
I believe the answer is:
ennoble
'maybe make peeress some' is the definition.
I can't tell whether this definition defines the answer.
'genteel bonnets in retirement' is the wordplay.
'in' indicates the answer is hidden within the clue.
'retirement' says the letters should be written backwards (retire can mean to return or go back).
'elbonne' is hidden in the letters of 'genteel bonnets'.
'elbonne' in reverse letter order is 'ENNOBLE'.
Can you help me to learn more?
(Other definitions for ennoble that I've seen before include "Noel Ben (anag)" , "Make a peer" , "Raise status" , "Aggrandise" , "Glorify - raise to the peerage" .)
