French boarding house cultivated no pines (7)
I believe the answer is:
pension
'french boarding house' is the definition.
(type of boarding house in France)
'cultivated no pines' is the wordplay.
'cultivated' indicates anagramming the letters.
'no'+'pines'='nopines'
'nopines' anagrammed gives 'PENSION'.
(Other definitions for pension that I've seen before include "Retirement pay in a Continental boarding-house" , "support for the elderly" , "residence abroad" , "Regular payment received after retirement" , "what oldies may have earned" .)
