This course covers the Hungarian indefinite conjugation, including the infinitive forms. The indefinite conjugation is used when the verb is intransitive (i.e. there is no direct object, as in 'to sleep'. You cannot say 'I sleep that', for example), it covers a very general statement ('I am reading'), or the direct object is undetermined ('We watch a butterfly' rather than 'We watch that butterfly').
For questions on anything, you can hit me up in the forum. Nem harapok - I don't bite.
