Kindly drop last rent (6)

I believe the answer is:

please

'kindly' is the definition.
(thesaurus)

'drop last rent' is the wordplay.
'last' indicates one should take the final letters.
'rent' becomes 'lease' (I've seen this before).
The final letter of 'drop' is 'p'.
'p'+'lease'='PLEASE'

(Other definitions for please that I've seen before include "Make cheerful" , "See 10 Across" , "Beatles song (request to oblige?)" , "See pal (anag) -- charm" , "Entertain" .)

I've seen this clue in The Guardian.
