Pausing points

Comma 
The comma might be the most troublesome punctuation mark. This is largely due to the many different ways the comma is used. Sometimes, the comma indicates a pause that would occur if the sentence were spoken aloud. Other times, the comma separates grammatical components of the sentence. Finally, there are mechanical and stylistic uses of the comma that are simply conventional. The presence or absence of a comma can change the meaning of a sentence⁠—sometimes dramatically. In extreme cases, an erroneous comma can make a sentence mean the exact opposite of what the writer intended. A careful writer must be a careful user of commas.

Semicolon 
The semicolon is sometimes described as stronger than a comma but weaker than a period. In certain uses, this is a reasonably accurate definition. Yet there is more to the semicolon than that.

Colon 
The colon has primarily three grammatical uses and several non-grammatical uses.
