Punctuation Marks
1. Period (.)
The period (.) is a fundamental punctuation mark in English grammar used to indicate the end of a declarative sentence or statement. It signals a full stop, allowing for a clear separation of ideas. The period is also used in abbreviations.

2. Comma (,)
The comma (,) is a versatile punctuation mark used to indicate a brief pause within a sentence. It helps clarify meaning by separating elements, such as items in a list, clauses, and adjectives. The comma also sets off introductory elements, direct addresses, and tag questions.
Rules to Use:
- Separate items in a list.

5. Colon (:)
The colon (:) is used to introduce a list, a quote, an explanation, or to separate two clauses when the second clause expands on or illustrates the first.

6. Semicolon (;)
The semicolon (;) is used to connect closely related ideas, linking independent clauses in a sentence without the use of a conjunction. It can also be used to separate items in a list where the items themselves contain commas.
Rules to Use:

7. Dash (—)
The dash (—), specifically the em dash, is used to create a strong break in the structure of a sentence. It can be used to add emphasis, introduce an element, or replace parentheses, commas, or colons.
