Slowly emerged as being nothing other than a fuddled doze (5)
I believe the answer is:
oozed
'slowly emerged' is the definition.
The definition and answer can be both to do with motion as well as being past participle verbs.
Maybe they are linked in a way I don't understand?
'being nothing other than a fuddled doze' is the wordplay.
'being nothing other than' becomes 'o' (I can't justify this - if you can you should believe this answer much more).
'a fuddled' indicates anagramming the letters.
'doze' anagrammed gives 'ozed'.
'o'+'ozed'='OOZED'
'as' is the link.
Can you help me to learn more?
(Other definitions for oozed that I've seen before include "Seeped" , "Exuded" , "Leaked out slowly" .)
