“Every day” is simply “all of the days”.
“Everyday” is an adjective meaning something extremely common or normal.
"Everyday" is an adjective, so it can only modify nouns whereas "Every day" is used as an adverb, thus can't mess up with nouns.
For example, Dragana writes two English essays every day; Dragana's everyday interest includes writing two essays and reading books(sorry Dragana if I am wrong:D)
Dragana, as far as I know, "continually" is used when we do something(or same thing)frequently after some time interval but "continuously" is something we do without taking any break.
For ex: The work is not done after doing it continually for one month.
The work is done after I put all my effort continuously for three hours.
This is what I think but if I am wrong please correct me.
then "every day" is the correct form.
Sudeep,
you guessed correctly my everyday interests. I write two essays and read three books daily. I am glad that someone finally noticed one of my superpowers. It usually takes only an hour of continuous work. When I am not involved in that kind of activity, I continually post long comments on this websites. I should get some credit for doing that, too. :)
