Punctuation is the system of symbols that we use to separate sentences and parts of sentences, and to make their meaning clear. Each symbol is called a punctuation mark.
For example (., ! – : etc)
Punctuation marks can be grouped into:
(i) End marks
(ii) The comma
(iii) The semicolon and the colon
(iv) The hyphen
(v) The apostrophe
(vi) Quotation mark
(i) End Marks
There are three kinds of end marks: the full stop (.), the question mark (?), and the exclamation mark (!).
End marks show where sentences end.
(a) The full stop (.)
A full stop is used to end a complete sentence.
We use a full stop to end:
A declarative sentence- a sentence that makes a state
- The highest skyscraper in Nairobi is Times Tower.
An imperative sentence – a sentence that makes a request or tells someone to do something.
Please climb the stairs carefully.
Note: An imperative sentence is followed by an exclamation mark when it expresses a strong emotion.
Example: Be careful!
At the end of an indirect question – one that tells what someone asked, without using the person’s exact words.
The naughty boy wanted to know why there was no mid-term break.
Other uses of the full stop
Full stops are also used:
After initials and after most abbreviations
L.L.Coo J. Mr. Sammy Njagi 11:00 A.M. Sept. Wed.
Note that some abbreviations do not require full stops:
M (metres), FM (frequency modulation), Km kilometres)
After each number or letter that shows a division of an outline or precedes an item in a list.

(b) The question mark (?)
The question mark is used at the end of an interrogative sentence (a sentence that asks a question).
When was the Times Tower built?
Who built it?
(c) The Exclamation mark (!)
The exclamation mark is used at the end of the exclamatory sentence and after an interjection.
(An exclamatory sentence expresses strong feeling, emotion or emphasis.
An interjection is a word or group of words that expresses strong feelings).
Exclamatory sentence: Oh, what a tall building it is! Interjections: Superb! Fantastic! Impressive! An exclamation mark can also be used at the end of an imperative sentence that expresses strong feeling.
Sit! And stay in that chair if you know what’s good for you!
(ii) The comma
There are a number of uses of the comma in English.
A comma generally tells the reader where to pause.
They are used: to separate words in a series except the last the three or four items in a series can be nouns, verbs, adjectives, adverbs, phrases, independent clauses, or other parts of sentences.
Nouns: John, Jim, Jack walk to school every day.
Verbs: He located, patched, and sealed the leak in the tyre.
Adverbs: She walked quickly, steadily, and calmly.
Prepositional phrases: He walked through the park, over the bridge, and onto the streets.
Independent clauses: The match was over, the crowd cheered, and Barcelona received the first- place trophy.
Adjectives: The fresh, ripe fruit was placed in a bowl.
Note in the above examples that a comma must be used just before the conjunction.
Before the conjunction in a compound sentence.
Some students were taking their lunch, but others were studying.
Marto photographed the accident scene, and he sold the pictures to the newspaper.
Would she be a lawyer, or would she be a doctor?
Note: A comma is not required in very short compound sentence in which the parts are joined by and.
However, always use a comma before the conjunctions but and or.
Marto photographed the accident scene and Toni reported it.
Marto photographed the accident scene, but Toni reported it.
Note also: A comma is not required before the conjunction that joins the parts of a compound verb unless there are more than two parts.
Mary entered and won the beauty contest.
That camera focuses, flashes, and rewinds automatically.
After introductory words phrases or clauses Special elements add specific information to a sentence, but they are not essential.
A comma is used to separate a special element from the rest of the sentence.
Word: Cautiously, he entered the building
Phrase: After his failure, he disappeared from the public scene.
Clause: Because he had practised daily, he presented his new song perfectly.
Note: If the pause after a short introductory element is very brief, you may omit the comma.
At first he was unsure of his singing ability.
Finally it was his turn.
Commas are also used after introductory words such as yes, no, oh and well when they begin a sentence.
Well, it’s just too cold out there.
No, it isn’t seven yet.
Oh, you have spilled the milk.
With interrupters, Interrupters are words that break, or interrupt the flow of thought in a sentence.
The commas are used before and after the interrupter to indicate pauses.
I didn’t expect, however, to lose the job.
So many people, assumed, sing as well as he does.
He was chosen, nevertheless, as the new band leader.
To set off nouns of direct address

Sarah, do you know where I kept my phone?
How is your leg, grandpa?
To set off the spoken words in a direct sentence or quotation from the speech tag
Jackson said, “After my injury I had to learn to walk again”.
“The therapists urged me to keep trying,” he continued.
If the speech tag interrupts the spoken words commas are used after the last word of the first part of the spoken words and after the last word in the speech tag.
“After a while,” he added, “I was walking without a cane”.
Note: When a sentence is indirect or reported, no commas are used.
He added that after a while he was walking without a cane.
When writing dates, place a comma after the day of the month.

(a) The semicolon (;)
The semicolon is used:
To separate the parts of a compound sentence when no conjunction is used.

Note that the semicolon replaces the comma and the coordinating conjunction.
Conjunctions that are commonly replaced by semicolons are and, but, or, for, and nor.
Before a conjunctive adverb that joins the clauses of a compound sentence (conjunctive adverbs are words like therefore, however, hence, so, then, moreover, nevertheless, yet, consequently, and besides).
