The Period (Full Stop)
The period, also called a full stop, is used to mark the end of a declarative sentence. It signals that a statement has been completed. Periods are also used in abbreviations.
Examples of sentences ending with a period:

The Comma
The comma is one of the most frequently used punctuation marks. It indicates a pause between parts of a sentence, separates items in a list, and clarifies meaning.
Common uses of commas include:
- Separating items in a series
- After introductory words or phrases
- Before conjunctions in compound sentences
- Setting off non-essential information

The Question Mark
The question mark is used at the end of direct questions. It indicates that a response or answer is expected.
It is important not to use a question mark after indirect questions or statements.

The Exclamation Mark
The exclamation mark expresses strong feelings such as surprise, excitement, or urgency. It is placed at the end of exclamatory sentences or interjections.

The Semicolon
The semicolon links closely related independent clauses that could stand as sentences on their own but are better connected for clarity or style. It can also separate items in a complex list where commas are already used.

Examples include:

- Introducing a quotation
- Separating hours and minutes in time
