Final answer:
The Latin phrase for the cast of characters in a play is 'Dramatis Personae.' It lists the characters at the start of a play, reflecting who will be portrayed.
Step-by-step explanation:
The two-word Latin phrase that denotes the cast of characters in a play is Dramatis Personae. This term is used to list the characters in a play, usually at the beginning, to help readers and the audience understand who will appear in the performance. Plays are organized by acts, scenes, and line numbers and may feature stage directions, though this is not always the case.
The plot tells a story, often involving conflict, and can be written in verse. In The Importance of Being Earnest by Oscar Wilde, for example, the persons in the play are listed under 'The Persons in the Play' which is characteristic of the Dramatis Personae format.
