Well, for what it's worth, here's my interpretation...bear in mind though, everyone will have slightly different ideas....

* fantasy worlds : aren't they the worlds tolkien made in his works ? aren't they the worlds that we try to write them down in many novels ? aren't they meaning a complete different world than ours ?

Close enough - usually different geography, history, and possibly life-forms, humanoid and non-humanoid (animals, birds, non-existent creatures, (dragons, orcs, ets.))

*parallel worlds : aren't they the worlds ( like magic worlds ) different than ours presented with our world at the same planet .. like rowling's harry potter , or the worlds that lie in different earthes like philip pullman dark materials ?

Yess...but the usual inference is that our world is running beside it, so to speak, and it's possible to switch between them.

*alternate worlds : i came by once with this name but frankly not knowing it's meaning !

Often, something was changed in history and the world in the story has fundimental differences to the real, present one. For example, a story set today, but Germany won WWII, so the Reich rules Europe.

*world building : isn't it the extensive work done in the novel to make many details of the world inside it and we write down only few details of it ..
or is it any set of world that the story occurs at and it's not like our world ?
tha latter one means that any fantasy novel has world building , like allis in the wonder land for example , right ?

Yes, good description. IMHO, the better the world building, the more believable the story.

*high fantasy : isn't it a type of fantasy tolkien sat its basis and is determined by the presence of world buildings or not .. or what ?

Not quite...I understand it to deal with themes that would alter the whole world...Evil Empires, Quests, etc. Magic swords, dragons, wizards, all nearly compulsory...[/quote]

Hope this helps...but do bear in mind that it is a personal view.

note : sorry that i bother you from time to time with questions i know you can answer it so easily , frankly speaking i tried hard to find the books you titled and some other friends titled me and others amazon did about the art of fantasy and its basis and really i can't fine any in egypt , i was shocked but i can't find any other source than you .. sorry !

Not a problem...one thing we're not short of here are people willing to give you their idea of what things mean.
