In bedroom, worker is asleep (7)
I believe the answer is:
dormant
'asleep' is the definition.
(similar in meaning)
'in bedroom worker' is the wordplay.
I cannot really understand how this works, but
'bedroom' could be 'dorm' (I have seen 'Communal bedroom ' mean 'dorm' so perhaps 'bedroom' could also mean 'dorm') and 'dorm' is present in the answer.
'worker' could be 'ant' (worker is a type of ant) and 'ant' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'is' is the link.
Can you help me to learn more?
(Other definitions for dormant that I've seen before include "Lying inactive as if in sleep" , "Sluggish" , "Inert" , "Temporarily quiet" , "In deep sleep" .)
