Present continuous tense with the time element "everyday"

Is it grammatical to use the present continuous when "everyday" is the time element involved, as in "I'm studying English everyday."?

Solution 1:

Yes, although it is more correct to separate the two words "every day." At least in standard US usage, "everyday" is an adjective:

She carried her everyday umbrella. She had a special one that she only used on Sundays.

For a daily action, we'd use "every day" as an adverb phrase.

I'm working hard in school. I am studying English every day.

Although there is no absolute reason to avoid the present progressive, many would prefer to omit -ing ending and say

I study English every day.

Please note that this is a descriptive answer, not a prescriptive one. Prescriptivists may raise their hackles as they will.
