Oozing a bit of liquid injected when unconscious (8)
I believe the answer is:
sleeping
'unconscious' is the definition.
(thesaurus)
'oozing a bit of liquid injected' is the wordplay.
'oozing' becomes 'seeping' (synonyms).
'a bit of liquid' becomes 'l' (I can't explain this - if you can you should believe this answer much more).
'injected' means one lot of letters goes inside another (inserted letters are injected).
'seeping' placed around 'l' is 'SLEEPING'.
'when' is the link.
Can you help me to learn more?
(Other definitions for sleeping that I've seen before include "Dormant" , "In the land of Nod" .)
