The tone you use when writing is most determined by your?

The tone you use when writing is most determined by your audience and purpose.

Here's why:

* Audience: Who are you writing for? A casual friend? A formal business contact? A wide range of readers? Your tone should be tailored to their interests, background, and expectations.

* Purpose: What are you trying to achieve with your writing? Are you informing, persuading, entertaining, or expressing yourself? Each purpose calls for a different approach.

While your personal writing style plays a role, it's ultimately the audience and purpose that should guide your tone choices.
