No, there isn't a resource specifically for explaining acronyms, but there are FAQs around the forums that would explain most of those anyways (and a lot more - like the one of this section - right at the topthe short term stuff, and D/P/Pt's section FAQ would as well I imagine -
https://www.pokecommunity.com/threads/199777)
Off the top of my head, main ones would be EVs (Effort Values - very briefly, fainting a Pokemon or feeding them Proteins, etc gives EVs, which go towards particular stats e.g. Attack. 4 = 1 stat point gain, you can get max 255 for one stat, max 510 total), IVs (Individual Values, range from 0-31, equivalent to 1 state point at level 100 so essentially the difference between bad and good IVs is fairly noticeable), STAB (Same type attack bonus - use a move that's the same type as the Pokemon and the move is 1.5 times stronger than normal e.g. Grass-poison type pokes get a STAB boost with grass and poison type attacks), SID (Secret ID - number game chooses which you can't see, can have effect on rng, etc, with rng being the random number generator, whic deals with stuff like whether a Pokemon is shiny, etc, etc)...
Of course if you do come across one not covered in an FAQ, then ask in the help thread. Above tend to be the main ones (unless you care about event Pokemon, there's a few more for those). Thread closed.
