Dragi prijatelju, srećan rođendan: the calling form and how to congratulate

You speak TO a person in a different form from the one you use ABOUT them. That is the calling form, and you hear it in every toast and every letter. For example: “Драги пријатељу, срећан ти рођендан и све најбоље” — Dear friend, happy birthday and all the best. A rule from the Serbian course: worked out on examples, not memorized as a wording.

How it works

You speak TO a person in a different form from the one you use ABOUT them. That is the calling form, and you hear it in every toast and every letter.

Masculine words after a hard stem take -e: drug → druže, brat → brate, gost → goste. After a soft stem they take -u: prijatelj → prijatelju, muž → mužu. Names in -o do not move: Marko → Marko.

Feminine words in -a take -o: Ana → Ano, majka → majko, gospođa → gospođo. Neuter words and every plural stay put: dete → dete, ljudi → ljudi.

The adjective goes along with the noun: dragi prijatelju, poštovani goste. You congratulate with čestitati: čestitam ti rođendan. And the wish itself is srećan in front of the occasion: Srećan rođendan!

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.
