Why do Americans write 'period' at the end of a sentence?

Question

? somtimes they say it too

Answer 1

its there version of a full stop

Answer 2

It is the same as full stop. But to emphisie a point, they say period, as in end of discussion, that is it, finished.
They shouldnt write it, that is just plain weird. But after all they are americans. :)

Answer 3

Proper English Grammar.

Answer 4

When we say period it means we absolutely think we are correct and there will be no change in our answer. Like if I say Joe Montana is the best quarterback ever. Period. It means ain't no one changing my mind about that.

Answer 5

americans dont exclusivley do this, everyone does!

its a way of enhancing word power, by speaking the full name of something you emphasise its importance.

instead of "john" you could say "Johnathan Alexander Jones!"
which sounds more effective?

a period = a full stop, but the american way of saying it.

i dont want you driving that car
i dont want you driving that car FULL STOP. which sounds stronger? americans just use period instead of full stop.

Answer 6

For emphasis. It means that what the person has said is beyond argument. It is sort of a polite way to say either shut up! or do it! or don't argue with me!

Answer 7

To emphasize the end of a statement. This end can sound jarring and lend gravitas to the former statement.

Answer 8

It's way of emphasizing "end of debate", "no qualifiers" or "no more discussion", mostly implies exhausting a subject.

e.g. "Gay people deserve the same rights as straight people, period"

Answer 9

I think they mean end of story. Like people over here tend to say end of.

Answer 10

Its their word for a full stop
