Cycle chain? (6)
I believe the answer is:
series
I believe this clue is a double definition.
'cycle' is the first definition.
(I've seen this before)
'chain?' is the second definition.
(thesaurus)
(Other definitions for series that I've seen before include "Sequence of programmes etc." , "Sets of programmes, stories etc" , "Similar things happening one after another" , "Progression of things" , "Number of similar things occurring in order" .)
