A few facts about (modern) Hungarian.
Hungarian has many different /Cases (esetek), most common are NominativeCase, AccusativeCase, DativeCase, InstrumentalCase, FinalCase, SupressiveCase, InessiveCase, ElativeCase, TerminativeCase, DelativeCase. There is also a FormalCase and a few other ones. I usually start learning a language by learning how to count and the days of the week. Here are /Numbers (számok).
The order of words in a sentence is not fixed, and can be used for stressing and denoting. Words can be combined (as in German) and derived (with suffixes and affixes).
The PassiveVoice is almost extinct (one can find it in old literary texts).
As an appetizer for a more complete vocabulary (szókincs), an extract for the verb "to be" in hungarian, lenni.

When you say the mark for the plural is "k," are you referring to verbs (as it seems) or nouns too? --RoseParks
Only for the nouns, although in many cases, conjugation of verbs looks similar.
Example: kérdés -- "question", kérdések -- "questions"; but három kérdés -- "three questions."
