The -ov-/-ev- Plural Infix | Croatian Grammar

One of the first things that surprises learners about Croatian masculine plurals is that "city" is gradovi, not *gradi, while "window" is prozori, not *prozorovi. The difference is the -ov-/-ev- infix — a chunk that a large group of (mostly one-syllable) masculine nouns inserts between the stem and the plural endings. It is sometimes called the "long plural." This page explains which nouns take it, why the choice between -ov- and -ev- is not random but governed by the same hard/soft consonant split that runs through the entire declension system, and the fact that the infix shows up in every plural case, not just the nominative. Learning it well here is a head start on the case system itself.

What the infix is

For a noun like sin ("son"), the plural is not built directly on sin-. Instead, the stem is expanded to sinov-, and then the regular plural endings attach to that expanded stem. Compare a "short plural" noun (prozor "window") with a "long plural" noun (grad "city") across a few plural cases:

Case (plural)	prozor (short)	grad (long)
Nominative	prozori	gradovi
Genitive	prozora	gradova
Dative/Locative/Instrumental	prozorima	gradovima

The endings (-i, -a, -ima) are identical for both nouns. The only difference is that grad carries -ov- in front of them all the way through. That is the heart of it: the infix is part of the plural stem, so once a noun has it, it has it everywhere in the plural.

Gradovi rastu, sela se prazne.

The cities are growing, the villages are emptying. — nominative plural gradovi.

Centar svih velikih gradova je preskup.

The centre of all big cities is too expensive. — genitive plural gradova, infix still present.

Putujemo između dvaju gradova autobusom.

We travel between the two cities by bus. — gradova again; the -ov- never drops in the plural.

Hard stems take -ov-, soft stems take -ev-

The choice between -ov- and -ev- is not arbitrary. It is decided by the last consonant of the stem — the same hard vs soft distinction that governs a great deal of Croatian morphology.

Hard stems (ending in most consonants: b, d, g, k, l, m, n, p, r, s, t, v, z…) take -ov-.
Soft (palatal) stems (ending in č, ć, đ, dž, š, ž, j, lj, nj, and usually c) take -ev-.

Singular	Stem-final consonant	Plural	Gloss
sin	-n (hard)	sinovi	son
grad	-d (hard)	gradovi	city
vol	-l (hard)	volovi	ox
vrh	-h (hard)	vrhovi	peak, top
muž	-ž (soft)	muževi	husband
kralj	-lj (soft)	kraljevi	king
nož	-ž (soft)	noževi	knife
prijatelj	-lj (soft)	—	friend (see below)

Kraljevi su nekad živjeli u ovom dvorcu.

Kings once lived in this castle. — soft stem -lj → -ev-: kraljevi.

Noževi su u gornjoj ladici.

The knives are in the top drawer. — soft stem -ž → -ev-: noževi.

Volovi polako vuku kola.

The oxen slowly pull the cart. — hard stem -l → -ov-: volovi.

💡

This is the single best reason to learn the infix at A2 rather than later: the -ov-/-ev- choice is the hard/soft split in miniature. The same rule decides instrumental singular -om vs -em (gradom vs mužem), vocative -e vs -u, and much of adjective declension. Master "hard → o, soft → e" here and you have learned a key that unlocks half the case system. See palatalization in declension.

A spelling subtlety: the -c- stems

Nouns whose stem ends in -c are interesting. The c is treated as soft, so it takes -ev-, but the c itself usually shifts to č before the front vowel — exactly the kind of softening you see elsewhere.

Singular	Plural	Gloss
stric	stričevi	(paternal) uncle
otac	očevi	father (also drops the fleeting -a-)
palac	palčevi	thumb

Moji stričevi žive u Splitu.

My uncles live in Split. — stric → stričevi: -c softens to -č and takes -ev-.

Which nouns take the infix — and which don't

This is where honesty is needed: there is no perfect rule for predicting the infix, only a strong tendency plus a list of exceptions you memorise.

The tendency: the long plural is the norm for monosyllabic masculine nouns. Most one-syllable masculines you meet — grad, sin, sat ("hour"), list ("leaf"), most ("bridge"), sok ("juice"), brod ("ship") — take it.

But several common monosyllables do NOT:

Singular	Plural	Gloss
dan	dani	day → days
konj	konji	horse → horses
prst	prsti	finger → fingers
gost	gosti	guest → guests
zub	zubi	tooth → teeth
crv	crvi	worm → worms

And longer nouns (two or more syllables) almost always take the short plural: prozor → prozori ("windows"), student → studenti ("students"), računalo… (that one's neuter, but the principle holds for automobil → automobili, profesor → profesori).

Dani postaju kraći u jesen.

The days are getting shorter in autumn. — dan → dani, NO infix despite being monosyllabic.

Konji pasu na livadi.

The horses graze in the meadow. — konj → konji, short plural.

Svi prozori gledaju na more.

All the windows face the sea. — disyllabic prozor → prozori, short plural is the default for longer nouns.

💡

There is no logical shortcut for the exception list — you must learn whether a given short noun is long-plural or short-plural the way you learn its gender: with the word. The safe default if you're stuck is: short masculine noun → try the -ov-/-ev- plural, because the long plural is the majority pattern. Then absorb the dan, konj, prst, gost, zub exceptions as a memorised set.

Doublets: when both are accepted

A handful of nouns genuinely allow both plurals, sometimes with a meaning difference, sometimes as free variants. These are not mistakes — they are lexicalised choices.

Singular	Both plurals	Note
put	putovi / putevi	"roads, ways" — both heard; putevi is very common
sat	sati / satovi	sati = "hours"; satovi = "clocks/watches" or "lessons"
list	listovi / listići	listovi = "leaves/sheets"; (note distinct diminutive too)

The sat split is worth knowing because it carries meaning: counting elapsed time you reach for sati, but physical clocks/watches or school lessons are satovi.

Čekao sam te dva sata.

I waited for you for two hours. — counting time: sat → sati family (here the paucal 'sata').

U trgovini prodaju zidne satove.

They sell wall clocks in the shop. — physical clocks: satovi (here accusative satove).

Stari putevi vode kroz planine.

The old roads lead through the mountains. — putevi, the common doublet of put.

How this differs from English

English builds the plural by tacking -s (or -es) onto the unchanged singular: city → cities, son → sons. The base word is untouched. Croatian's long plural does something English has no equivalent for: it rebuilds the stem before adding the ending, and it does so consistently across all the plural cases. The closest English analogue is irregular plurals like child → children (where -r- + -en is added), but those are scattered leftovers, whereas the Croatian -ov-/-ev- infix is a living, productive pattern affecting a whole class of words — and the soft/hard choice within it has no English parallel at all, because English consonants are not sorted into hard and soft for grammatical purposes.

Common mistakes

❌ Veliki gradi na sjeveru.

Incorrect — 'grad' takes the long plural; the form is 'gradovi'.

✅ Veliki gradovi na sjeveru.

The big cities in the north. — gradovi with -ov-.

❌ Stari kraljovi.

Incorrect — 'kralj' has a soft stem (-lj), so it takes -ev-, not -ov-.

✅ Stari kraljevi.

The old kings. — soft stem → -ev-: kraljevi.

❌ Sedam danova u tjednu.

Incorrect — 'dan' is an exception: its plural is 'dani', no infix.

✅ Sedam dana u tjednu.

Seven days in a week. — here the genitive plural 'dana' after 7; the plural stem is dan-, never dani-/danov-.

❌ Svi prozorovi su otvoreni.

Incorrect — 'prozor' is disyllabic and takes the short plural 'prozori'.

✅ Svi prozori su otvoreni.

All the windows are open. — prozori, short plural.

❌ Dao sam novac mužovima.

Incorrect — soft stem 'muž' takes -ev- everywhere in the plural: muževima.

✅ Dao sam novac muževima.

I gave money to the husbands. — dative plural muževima, soft -ev- infix retained.

Key takeaways

The -ov-/-ev- infix ("long plural") inserts between the stem and the plural endings, and appears in every plural case (gradovi, gradova, gradovima).
Hard stems take -ov- (sin → sinovi); soft/palatal stems take -ev- (muž → muževi, kralj → kraljevi) — the same hard/soft split that runs through the whole declension.
The long plural is the norm for monosyllabic masculines, but disyllabic nouns take the short plural (prozor → prozori), and several common monosyllables are exceptions: dan → dani, konj → konji, prst → prsti, gost → gosti, zub → zubi.
Some nouns have doublets (put → putovi/putevi; sat → sati "hours" vs satovi "clocks/lessons").
There is no flawless rule for membership — learn it with the word, defaulting short masculines to the long plural when unsure.
