I believe the answer is:
episodes
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">parts of a serial</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for episodes that I've seen before include "Incidents or events as in a story" , "So espied in parts of stories" , "Occurrences in a series" , "Sections of a serial" , "Instalments" .)
