Vocative: Masculine Nouns | Croatian Grammar

Masculine nouns build their singular vocative with one of two endings — -e or -u — and the choice is decided by the final sound of the stem. The -e ending carries a bonus that makes this page do double duty: it triggers velar softening, the same consonant change you meet across the noun and verb system, so Bog becomes Bože and junak becomes junače. Learn the -e/-u split and the softening it sets off, and you will both address Croatian men correctly and drill one of the language's core sound rules at the same time.

The core decision: -e or -u

The rule is about the last consonant of the stem.

Hard-stem masculines — those ending in a "hard" consonant — take -e: Ivan → Ivane, gospodin → gospodine, brat → brate.
Soft (palatal) stems — those ending in -j, -lj, -nj, -č, -ć, -š, -ž, -c, -đ, -dž — take -u: prijatelj → prijatelju, muž → mužu, kralj → kralju.

Ivane, javi se kad stigneš.

Ivan, let me know when you arrive. — hard stem 'Ivan' → vocative 'Ivane' (-e).

Gospodine, zaboravili ste kišobran.

Sir, you've forgotten your umbrella. — 'gospodin' → 'gospodine' (-e).

Prijatelju, dugo se nismo vidjeli!

My friend, we haven't seen each other in ages! — soft stem in -lj → 'prijatelju' (-u).

Mužu, gdje su ti ključevi?

Husband, where are your keys? — soft stem 'muž' (ž) → 'mužu' (-u).

💡

The split is purely phonological: if the stem ends in a soft/palatal consonant (the hushing and palatal sounds, plus c and j), use -u; otherwise use -e. You can hear it — -u sits comfortably after j, lj, nj, č, ć, š, ž, where -e would feel forced.

The -e ending triggers velar softening

This is the linguistically rich part. When -e is added to a stem ending in a velar consonant — k, g, h — that consonant softens before it:

Velar	Softens to	Example
k	č	junak → junače (hero!), vojnik → vojniče (soldier!)
g	ž	Bog → Bože (God!), vrag → vraže (devil!)
h	š	duh → duše (spirit!), siromah → siromaše (poor wretch!)

Bože, daj mi snage.

God, give me strength. — 'Bog' → 'Bože': g softens to ž before -e.

Junače moj, što si učinio?

My hero, what have you done? — 'junak' → 'junače': k softens to č before -e.

Duše nemirni, smiri se.

Restless spirit, calm down. — 'duh' → 'duše': h softens to š before -e. (literary)

This is the same softening (the first palatalisation) that you see in plurals, in verb conjugation, and elsewhere — the velars k, g, h turn into č, ž, š when an -e (or certain other front vowels) follows. The vocative is one of the cleanest places to practise it, because the trigger is so reliable. For the full pattern across the grammar, see palatalisation in declension.

💡

Don't memorise Bože and junače as isolated oddities — they obey a rule you'll meet again and again: k → č, g → ž, h → š before -e. Once you internalise the rule, dozens of forms across the language stop being surprises.

A special case: stems in -c take -e with softening

Nouns ending in -c behave in a way that surprises learners. Although c is a "soft-ish" sound, many common -c nouns take -e and soften the c to č (the same first palatalisation):

Striče, donio sam ti dar.

Uncle, I've brought you a gift. — 'stric' → 'striče': c softens to č before -e.

Oče, blagoslovi nas.

Father, bless us. — 'otac' → 'oče' (a high-frequency irregular: the -a- drops and c → č). (formal/literary)

So stric (uncle) → striče, otac (father) → oče, lovac (hunter) → lovče. This is worth singling out because the obvious guess (stricu) is wrong for these words.

High-frequency address forms

These are the masculine vocatives you will actually say and hear. Memorise them as ready-made words:

Nominative	Vocative	Meaning (address)
gospodin	gospodine	Sir / Mr
prijatelj	prijatelju	(my) friend
čovjek	čovječe	man! / mate! (k → č)
sin	sine	son
otac	oče	father
brat	brate	brother / bro
Bog	Bože	God (g → ž)
doktor	doktore	doctor

Čovječe, pa to je nevjerojatno!

Man, that's incredible! — 'čovjek' → 'čovječe' (k → č), used as a casual exclamation. (informal)

Sine, jesi li ručao?

Son, have you had lunch? — 'sin' → 'sine' (-e).

Doktore, boli me ovdje.

Doctor, it hurts here. — 'doktor' → 'doktore' (-e).

💡

Brate! ("bro!") and čovječe! ("man!") are everyday conversational fillers, much like English "mate" or "dude" — you'll hear them constantly among friends. Note they're vocatives even when nobody's literal brother or a stranger is involved. (informal)

Proper names: what's regular, what isn't

Most male names follow the hard-stem -e rule cleanly: Ivan → Ivane, Petar → Petre (with the fleeting -a- dropping), Tomislav → Tomislave, Stjepan → Stjepane. Names ending in a soft consonant take -u: Matej → Mateju.

Petre, čekaju te vani.

Petar, they're waiting for you outside. — 'Petar' → 'Petre' (fleeting -a- drops, then -e).

But two big groups of names do not change:

Names ending in -o: Marko, Darko, Mirko, Branko stay exactly as they are — Marko → Marko. The -o already does the addressing work, so no ending is added.
Familiar/short names in -a: Ivica, Jure, Mate and hypocoristics in -a typically stay put or follow feminine-style patterns; in everyday speech they're usually left unchanged.

Marko, jesi li gotov?

Marko, are you done? — names in -o don't change in the vocative.

Darko, dođi na večeru!

Darko, come to dinner! — 'Darko' is unchanged.

💡

The safe defaults for names: consonant-final → add -e (Ivane, Petre, Stjepane), -o → no change (Marko, Branko), soft consonant → add -u (Mateju). When in doubt with a man's name in -o, leave it alone — adding an ending there is the actual error.

Common mistakes

❌ Bog, daj mi snage.

Incorrect — addressing God needs the vocative 'Bože' (g → ž), not the nominative 'Bog'.

✅ Bože, daj mi snage.

God, give me strength. — vocative with velar softening.

❌ Prijatelje, dugo se nismo vidjeli!

Incorrect — soft stems in -lj take -u, not -e: 'prijatelju'.

✅ Prijatelju, dugo se nismo vidjeli!

My friend, long time no see! — soft stem → -u.

❌ Markoe, jesi li gotov?

Incorrect — names in -o stay unchanged in the vocative; you don't add an ending.

✅ Marko, jesi li gotov?

Marko, are you done? — '-o' name unchanged.

❌ Stricu, donio sam ti dar.

Incorrect — '-c' stems like 'stric' take -e with softening: 'striče' (c → č), not -u.

✅ Striče, donio sam ti dar.

Uncle, I've brought you a gift. — c softens to č before -e.

❌ Čovjeku, pa to je nevjerojatno!

Incorrect — 'čovjek' takes -e with k → č softening: 'čovječe', not -u.

✅ Čovječe, pa to je nevjerojatno!

Man, that's incredible! — velar k softens to č before -e.

Key takeaways

Masculine singular vocative ends in -e (hard stems: Ivane, gospodine, brate) or -u (soft/palatal stems in -j, -lj, -nj, -č, -ć, -š, -ž: prijatelju, mužu, kralju).
The -e ending softens a final velar: k → č (junak → junače), g → ž (Bog → Bože), h → š (duh → duše) — the same first palatalisation found across the grammar.
-c stems take -e with c → č: stric → striče, otac → oče — not the -u you might expect.
Memorise the everyday forms: gospodine, prijatelju, čovječe, sine, brate, oče, Bože, doktore.
Names in -o don't change (Marko → Marko); consonant-final names add -e (Ivane, Petre); adding an ending to an -o name is the classic error.
