>>As it is... I really don't see why was it introduced at all. It, like, looks like a pointless, like, fad.

>So is the word "everyday", which I think means different from "every day".

I figure "everyday" is an adjective, while "every day" would serve as an adverb. IOW, something can be an everyday thing, or can be done every day.

>When people use "everyday" as in "I go swimming everyday",

...so this example would be wrong, "I go swimming every day", but "swimming is an everyday activity".

>they may not literally mean "every day". They may mean "regularly" as in "I go swimming regularly", which may mean they go swimming once every week or once a month on a regular basis. :)

And skip it on an irregular one?
