turn

I'm a little stuck... Click here to teach me more about this clue!

I believe this is a quadruple definition!!

'change' is the first definition.
(I know that turn is a type of development)

'item' is the second definition.
The definition and answer can be both related to communication as well as being singular nouns.
Perhaps there's a link between them I don't understand?

'in' acts as a link.

'variety' is the third definition.
(thesaurus)

'show' is the fourth definition.
(I know that turn is a type of performance)

Can you help me to learn more?
