Course to be taken as indicated when out of bed (4)
I believe the answer is:
soup
'course' is the definition.
(I've seen this before)
'taken as indicated when out of bed' is the wordplay.
I cannot really see how this works, but
'as' could be 'so' (I've seen this in other clues) and 'so' is found in the answer.
'out of bed' could be 'up' (synonyms) and 'up' is found in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'to be' acts as a link.
Can you help me to learn more?
(Other definitions for soup that I've seen before include "Liquid - course" , "Eg, mulligatawny" , "Eg, potage, broth" , "Mulligatawny or borscht?" , "First course" .)
