Finnish and Hungarian, despite being spread well apart from each other, are from the same Uralian language family.

Both (and other languages in the family) share one distinctive feature – an excessively large number of noun cases (by Indo-European language family standards).

However, these languages do not have prepositions, i.e. the 16-20 odd noun cases replace them, so it makes it somewhat easier for a new learner.

The noun cases can also be thought of as postpositions despite obviously not being them, but it is a good and simple mental model.

The real outlier is Icelandic, which has a notoriously irregular grammar, multiple noun declension and verb conjugation groups, prepositions and postpositions despite a small number of noun cases.
