Be put back in bed, having gone into decline (5)
I believe the answer is:
ebbed
'gone into decline' is the definition.
I can't tell whether this defines the answer.
'be put back in bed' is the wordplay.
I cannot quite see how this works, but
'be' is present in the answer.
an anagram of 'bed' is 'ebd' which is located in the left over letters.
This accounts for all the letters.
This explanation may well be incorrect...
'having' acts as a link.
Can you help me to learn more?
(Other definitions for ebbed that I've seen before include "Flowed back or receded" , "Went out like tide" , "Diminished" .)
