Could you help me with examples of speaker-oriented and reader-oriented language rules or name the literature where i can find information about it?

Speaker-oriented language rules focus on how the speaker communicates their message, while reader-oriented language rules focus on how the reader understands the message. You can find information on this topic in pragmatics and discourse analysis literature, such as "Pragmatics" by George Yule or "Discourse Analysis" by Gillian Brown and George Yule.
