Punctuation is used to separate words into sentences and clauses to clarify meaning. Punctuation marks like commas and question marks are signals to readers that help convey meaning since tone of voice cannot be used in writing. The most common punctuation marks are the period, question mark, and exclamation mark. A period is used at the end of declarative sentences and to end abbreviations. A question mark is used at the end of interrogative sentences that ask a question. An exclamation mark is used to show strong emotion or emphasis at the end of a sentence or after an interjection expressing feeling at the start of a sentence.

1. Punctuation is the use of standard marks and signs to separate words into sentences and clausesto
clarify meaning. The marks or signs are called punctuation marks. Punctuation marks are signals to
readers. When you speak, you can pause, stop, or change your tone of voice to make your meaning
clear. You cannot do this when you write. When writing, you must use punctuation marks such as
commas and question marks to make your meaning clear.
The use of punctuation marks can be very complex. Each punctuation mark can be used in many ways.
