Humbled, as in a place to retire to (6)
I believe the answer is:
abased
'humbled' is the definition.
('abase' can be a synonym of 'humble')
'as in a place to retire to' is the wordplay.
'in' indicates putting letters inside.
'place to retire to' becomes 'bed' (I've seen this in another clue).
'a'+'bed'='abed'
'as' inserted into 'abed' is 'ABASED'.
(Other definitions for abased that I've seen before include "Degraded, brought low" , "Humiliated or degraded" , "Demeaned (oneself)" , "Humbled, mortified" , "Belittled, degraded" .)
