Occasional copies I'd botched (8)
I believe the answer is:
episodic
'occasional' is the definition.
('episodic' can be a synonym of 'occasional')
'copies i'd botched' is the wordplay.
'botched' indicates anagramming the letters.
'copies'+'id'='copiesid'
'copiesid' anagrammed gives 'EPISODIC'.
(Other definitions for episodic that I've seen before include "Serialised" , "Occurring irregularly - is copied thus" , "Occurring at irregular intervals" , "Discursive" , "Intermittent" .)
