Looking for guide for all the terminology and abbreviations, ETC

Hey guys ive been a way for a long time and WOW has certainly changed a lot. I just recently started playing again and i feel completely lost and its pushing me way from the game.

i am looking for help with relearning all the terminology related to any aspect of the game and definitions for what everything means so i can better understand what i am looking at. seriously so much has changed since 2006 its insane.

If anyone can please point me in the right direction then it would be deeply appreciated.
