Terminal punctuation: period (AmE) / full stop (BrE) (.)
The period (.) is used to mark the end of two types of sentences:
Declarative sentences (sentences which give information)
I teach English.
We had pizza for dinner last night.
If it rains tomorrow, I’ll bring my umbrella.
Imperative sentences (commands or requests)
Please don’t feed the animals.
Let me know what time your flight arrives. If it rains tomorrow, bring your umbrella.
Terminal punctuation: exclamation mark (!)
The exclamation mark (!) is
used to convey strong emotion:
I’m really excited about my new job. (no emotion)
I’m really excited about my new job! (excitement)
If you come to work late tomorrow, you’re fired! (anger)
Johnny, don’t play with your food! (strict command)
Ouch! You just stepped on my foot! (pain)
Wow! What a beautiful house!(amazement)
Terminal punctuation: question mark (?)
The question mark (?) is used to mark the end of a question:
What do you do?
Are we allowed to feed the animals?
If it rains tomorrow, should I bring my umbrella?
Are you excited about your new job?
Who lives in that house?

Notice that there is no space between the last letter of a sentence and the terminal
punctuation mark.
If you put a space there, it’s wrong.
But, when you begin a new sentence, you should leave a space after the terminal mark, and
you should start the new sentence with a capital letter.

Whenever you connect two independent clauses in the same sentence, you must put a comma
after the first one.
But that’s not enough.
You must use a word like ‘and’, ‘but’, ‘or’, or ‘so’ to connect the clauses
– these words are called coordinating conjunctions (coordinating just means connecting).
Common error!
