Is Mister spelled out or abbreviated in formal writing?

Here's why:

* Formal tone: Abbreviating titles like "Mister" to "Mr." is considered less formal.

* Clarity: Using the full word "Mister" avoids any potential confusion with other titles like "Ms." or "Mrs."

Example:

* Formal: "Mister Smith is a respected member of the community."

* Informal: "Mr. Smith is a respected member of the community."

Note: While "Mr." is widely accepted in informal writing, it's best to stick to the full spelling of "Mister" in formal settings like academic papers, legal documents, or business correspondence.
