Since the word contact means to squeeze together, it seems only logical that a contraction is two words made shorter by placing an apostrophe where letters have been omitted. Examples of common contractions in the English language include:
I'm: I am
Can't: can not
We've: we have
She'll: she will
He's: he is
They'd: they would
Won't: will not
Weren't: were not
Wasn't: was not
Wouldn't: would not
Shouldn't: should not
Isn't: is not
Technically speaking, contractions aren't necessary in written English. Using the full version of a word is always grammatically correct. However, there are a number of reasons why contractions do serve a valuable stylistic purpose. For example:
Contractions make your writing seem friendly and accessible. They give the appearance that you are actually "talking" to your reader.
When writing dialogue in a novel or play, contractions help reflect how a character actually speaks.
Contractions help to save space when preparing advertisements, slogans, and other written works that must be short and to the point.
