Learn French: La didascalie indique que le comédien doit murmurer. - The stage direction indicates that the actor must whisper.

There is no inversion because this sentence uses indirect speech, introduced by que. Inversion in reporting clauses (like « ... », indique la didascalie) is only used when reporting direct speech—quoting someone's exact words or instructions.

How could we rewrite this sentence as direct speech to include an inverted reporting clause (une incise)?

You would write the exact instruction as a quote, followed by the inverted verb and subject at the end or in the middle. For example: « Le comédien doit murmurer », indique la didascalie. Notice how the verb indique now comes directly before the subject la didascalie.

What is the difference between "un comédien" and "un acteur"?

While they are often used interchangeably in everyday French, un comédien technically refers to a stage actor performing in a theatrical play. This fits perfectly with this sentence's context. Un acteur is a more general term, but it is heavily associated with film and cinema.

Is "didascalie" a common everyday word in French?
