The language register is the appropriate level and style of your writing or also the language you use in specific situation depending on the people you are talking with.  It determines the vocabulary  and the structure and grammar of the text or conversation.

The three most common language registers in writing are:

• Formal
• Informal
• Neutral

The formal register is more appropriate for professional writing and letters to a boss or a stranger. 

The informal register (also called casual or intimate) is conversational and appropriate when writing to friends and people you know very well.

The neutral register is non-emotional and sticks to facts. It is most appropriate for technical writings.

To your friends: What's up? It's awesome that you came over!

To the President of the United States: Good morning, Mr. President. We appreciate your visit.
