"Hi, how is it going?"
Translation:Hoi, hoe gaat het?
Yep, it's the third person singular conjugation (so for het, dat, hij, zij and ze), and "ga" is the first person. Don't quote me on this, but I'm pretty sure the second person is "gaat" as well, and the infinitive is "gaten" (because spelling rules, but as I said, no quoting).
EDIT: "Gaan" is the infinitive. Which is defs much cooler.
