Does Google recognize an abbreviation, in second half of two part names?

dolphinar.com (dolphin animal rights, but “ar” could stand for other things)

At the least, will G now to seperate the “dolphin” term even if AR/animal rights is not spelled out anywhere on the site?

Google will not assume “ar” stands for anything. That domain will only really help you if someone searches “dolphinar”. The search engine doesn’t maintain some dictionary that it tries to match against parts of domains.
