Is avatar the last airbender an anime?

No.
Avatar is my new پسندیدہ Melodic Death Metal band.

No, عملی حکمت is made in Japan, I believe avatar was made in America

In a way, no. Avatar wasn't made in Japan, so in countries other than Japan it is not considered an anime. But in Japan, "anime" refers to any form of اندازی حرکت regardless of nationality. Therefore, in Japan, it is considered an anime. It is not considered an عملی حکمت in other countries such as the United States.

its combined with a عملی حکمت and a cartoon so its a cartoon and a anime.

Not technically. It has an anime-like drawing style. But it wasn't made in Japan.

But kelly1412 has some really cool anime-avatar fanart.

It's sort of a confusing choice between cartoon and anime, since عملی حکمت refers to اندازی حرکت made in Japan and Avatar was made in America it would make مزید sense for it to just be a cartoon.

Yes it is ._.
Because it is animation.

عملی حکمت means Japanese اندازی حرکت so no it most certainly is not an anime.

Well, "anime" is the Japanese word for cartoons and animation, so, in a way, yes, but عملی حکمت really refers to the Japanese made cartoons, so in another way--no.
