What is a period punctuation mark?
Any sentence meant to make a statement should end with a period, a little dot-shaped punctuation mark. The period should be positioned precisely behind the final letter of the sentence's final word, much like other punctuation marks used to terminate sentences.
Alternatively, the symbol can be used alone to denote omitted characters or repeatedly as an ellipsis (...) to denote omitted words. It may be positioned after the first letter of a name or after each letter in an initialism or acronym (e.g., "U.S.A."). Meanwhile, the use of full stops following acronyms or initialisms is waning, and many of them sans punctuation have established themselves as standard practice (e.g., "UK" and "NATO"). Compared to other English-speaking countries, the United States has seen a somewhat slower progression of this tendency.
How to Use Periods?
Place a single space after a period at the conclusion of a sentence before starting the following one. This guideline has only been in effect since word processing software became widely used; in the past, when people still used typewriters, one would place two spaces after periods and other sentence-ending punctuation.
Additionally, periods are used with abbreviations.
The period that follows an abbreviation that concludes a statement, a directive, or an indirect question is also used to finish the sentence.
Even though they are abbreviations, acronyms typically don't need periods. You don't need to include periods between the letters if you're using an acronym that sounds like a word, like NOW, NATO, RADAR, or SCUBA. Periods may or may not be necessary if you are using an acronym that is spoken by speaking the letters one at a time. Instances include the FBI, NBA, NCAA, NAACP, USA, and UNICEF.
