What type of speech is predecessors?

"Predecessors" is not a type of speech. It's a noun that refers to people who held a position before someone else.

To understand what type of speech you might be referring to, please provide more context. For example:

* Are you asking about a type of speech that mentions predecessors? (e.g., a speech about the history of a company, a speech by a new leader acknowledging past leaders)

* Are you looking for a synonym for "predecessor" that describes a type of speech? (e.g., "forerunner", "pioneer" - these terms are sometimes used to describe early examples of something, like a genre of music or a style of writing)

Once you give me more details, I can help you figure out what you mean.
