PUNCTUATION IS USED TO CREATE SENSE, CLARITY AND STRESS IN SENTENCES

You use punctuation marks to structure and organise your writing. The most common of these are the period (or full stop in British English), the comma, the exclamation mark, the question mark, the colon and semi-colon, the quote, the apostrophe, the hyphen and dash, and parentheses and brackets. Capital letters are also used to help us organise meaning and to structure the sense of our writing.

You can quickly see why punctuation is important if you try and read this sentence which has no punctuation at all:

Perhaps,you dont always need to use commas periods colons etc to make sentences clear when i am in a hurry tired cold lazy or angry i sometimes leave out punctuation marks grammar is stupid i can write without it and dont need it my uncle Harry once said he was not very clever and i never understood a word he wrote to me i think ill learn some punctuation not too much enough to write to Uncle Harry he needs some help.

let's see if punctuation it makes a difference!

Perhaps you don't always need to use commas, periods, colons etc. to make sentences clear. When I am in a hurry, tired, cold, lazy, or angry I sometimes leave out punctuation marks. "Grammar is stupid! I can write without it and don't need it." my uncle Harry once said. He was not very clever and I never understood a word he wrote to me. I think I'll learn some punctuation - not too much, enough to write to Uncle Harry. He needs some help! Use the punctuation section to learn how to make your English clearer and better organised.
