Greetings, I know that if I want to introduce a book to someone and tell them about some pages, I should use "chapter". For the serial which are related to each other and contain a whole body, I use "episode". But I don't know what word should be used for a TV program which is shown every night but they are not related and each episode contains a different story. Is it still episode? I found this somewhere here: Series (original meaning): A set of separate stories involving the same principal characters and theme. Each episode is a complete story, with its own plot. Serial (now generally called a series): A continuous story, shown in a number of parts (episodes). The main plot runs continuously through successive episodes, for at least a whole season. But my question still stands. I want to know the word English people use for some part of a program not the whole 1 hour- program.
