Occasional ratbag and I awesome to behold (8)
I believe the answer is:
episodic
'occasional' is the definition.
(I know that occasional can be written as episodic)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for episodic that I've seen before include "taken one piece at a time" , "Discursive" , "Arranged as a series of incidents" , "Presented in sections" , "Is copied in irregular occurrence" .)
