Notes awful bile isn’t too bad (6)
I believe the answer is:
edible
'isn't too bad' is the definition.
I can't tell whether this definition defines the answer.
'notes awful bile' is the wordplay.
'notes' becomes 'ed' ().
'awful' is an anagram indicator.
'bile' with letters rearranged gives 'ible'.
'ed'+'ible'='EDIBLE'
Can you help me to learn more?
(Other definitions for edible that I've seen before include "Comestible" , "Digestible" , "Fit to be used as food" , "Belied (anag)" , "Fit to eat" .)
