Prepared cod pies, eating one from time to time (8)
I believe the answer is:
episodic
'time to time' is the definition.
I can't tell whether this definition defines the answer.
'prepared cod pies eating one' is the wordplay.
'prepared' is an anagram indicator.
'eating' is an insertion indicator.
'one' becomes 'i' (Roman numeral).
'cod'+'pies'='codpies'
'codpies' is an anagram of 'episodc'.
'episodc' placed around 'i' is 'EPISODIC'.
'from' acts as a link.
Can you help me to learn more?
(Other definitions for episodic that I've seen before include "Discursive" , "taken one piece at a time" , "in serial form" , "Sporadic" , "piecemeal" .)
