Dot vs. Period: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Updated on November 7, 2023
A dot is a small round mark, while a period is a dot used to signal the end of a sentence or an interval of time.
Key Differences
A dot is a small, distinct circular mark used in various contexts, from punctuation to decoration. In contrast, a period is a specific type of dot that concludes sentences in English grammar or represents a full stop in other applications.
The term dot can refer to elements in digital screens, art, or patterns, not limited to text. A period, however, is a grammatical punctuation mark, also serving as a decimal point or in abbreviations within written language.
Dots are versatile and can be found in diverse fields such as mathematics, where they indicate multiplication, and fashion, as in polka dots. Periods are strictly used in written language, denoting the end of declarative sentences or an abbreviation.
In computing, dots are used in domain names and file extensions, while periods are used in programming languages to separate objects and methods, also acting as full stops in written code comments.
The word dot is also used as a verb meaning to make a small mark, whereas period does not serve as a verb but as a noun, referring to a punctuation mark or a span of time.
