They're drawn back to bed a lot (7)
I believe the answer is:
doodles
'they're drawn' is the definition.
The definition suggests an adverb but the answer is not.
'back to bed a lot' is the wordplay.
'back to' says to take the final letters.
'a lot' becomes 'oodles' (oodles means a large amount).
The final letter of 'bed' is 'd'.
'd'+'oodles'='DOODLES'
Can you help me to learn more?
(Other definitions for doodles that I've seen before include "Scribbles absent-mindedly" , "Scribbled drawings" , "makes drawings absentmindedly" , "Idle drawings" , "rough sketches" .)
