A full stop or period.

A full stop is also known as a full point,[1] or period.[2] It is a punctuation mark (.) at the end of a sentence. It shows that the sentence has finished. To be a sentence it must have at least one complete clause, with a verb and a subject.[3]

When it is used in numbers, it is called a decimal point. It shows that the numbers to the right of it are less than one, as in 1.234. When it is used to write money in numbers, it shows that the numbers to the right of it are less than one pound/dollar/euro. For example:

"Elizabeth bought a soda for $1.28."

means that Elizabeth paid one dollar and twenty-eight cents for her drink.

A point may be used after a word has been shortened: Pty. Ltd. The words doctor, mister, and mistress are often made shorter when used with a name. "Dr. Smith" is the name of a doctor whose last name is Smith, and "Mr." Banerjee is short for Mister Banerjee. "Mrs" means a wife, "Miss" is an unmarried female. "Ms" can be used for either. An initial is also used for names when the first and middle name are shortened but the last name is not, for example "J. Citizen".

When three periods are used together (...), they are called an ellipsis.
