Recently allowed back in bed (6)
I believe the answer is:
lately
'recently' is the definition.
('lately' can be a synonym of 'recently')
'allowed back in bed' is the wordplay.
'allowed' becomes 'let' (I've seen this before).
'back' is a reversal indicator.
'in' means one lot of letters goes inside another.
'bed' becomes 'lay' (I've seen this before).
'let' back-to-front is 'tel'.
'tel' inserted inside 'lay' is 'LATELY'.
(Other definitions for lately that I've seen before include "Not long ago, in recent times" , "Recently" , "Within recent time" , "In the recent past" , "In the last few days" .)
