Orodnik: the “with what” case and why it always carries z or s

The 'with what' form almost never goes without a preposition. English cuts bread 'with a knife'; Slovenian says režem z nožem, merim z metrom, pišem s svinčnikom. For example: “Kruh je narezal z ostrim nožem” — He cut the bread with a sharp knife. A rule from the Slovenian course: worked out on examples, not memorized as a wording.

How it works

The 'with what' form almost never goes without a preposition. English cuts bread 'with a knife'; Slovenian says režem z nožem, merim z metrom, pišem s svinčnikom.

S stands before a voiceless consonant, z before everything else and before vowels: s prijateljem, but z bratom.

The endings are short. Masculine and neuter take -om: z nožem, z avtom. Feminine takes -o: z roko, z vodo. In the plural, -i and -ami: z noži, z rokami. About two, -oma: z rokama, z bratoma.

The same form follows pred, nad, pod, med: pred hišo, nad mizo, med sosedoma. A feminine word ending in a consonant takes -jo: z močjo, s plastjo.

How the rule settles in your head

A rule is not memorized from an explanation. It is memorized from an attempt to use it and a mistake — that is why the app delivers it mixed in with words, not as a separate lesson: it resurfaces exactly where you forgot it.
