Feminine Noun Declension | Croatian Grammar

Croatian has two feminine declensions, and they look so unalike that beginners constantly mistake one of them for masculine. This page puts them side by side so the relationship is obvious: the large -a declension (žena, knjiga) and the smaller but very common i-declension of consonant-final feminines (noć, stvar). Seeing them together is the cure for the single most frequent gender error in Croatian — treating noć ("night") as masculine because it ends in a consonant.

The two model nouns

žena ("woman") — the -a declension: a feminine noun ending in -a in the dictionary form. This is the big, regular class.
noć ("night") — the i-declension: a feminine noun ending in a consonant. Smaller, but full of high-frequency words (noć, stvar, ljubav, riječ, kost, radost).

We will also bring in knjiga ("book") and ruka ("hand") at the right moments to show what happens when the stem ends in k, g, h.

Singular

Case	žena (-a declension)	noć (i-declension)
Nominativ	žena	noć
Genitiv	žene	noći
Dativ	ženi	noći
Akuzativ	ženu	noć
Vokativ	ženo	noći
Lokativ	ženi	noći
Instrumental	ženom	noći / noću

Look at the i-declension column: from the genitive down, almost every form is just noći. The i-declension singular is remarkably flat — four of its seven cases (gen, dat, loc, and the alternative instrumental) end in -i, the accusative equals the nominative, and only the instrumental offers a choice. The -a declension, by contrast, gives each case its own ending.

Ta žena radi u banci.

That woman works at the bank. — nominative subject.

Bojim se mraka i noći.

I'm afraid of the dark and of the night. — genitive 'noći' after 'bojati se'.

Volim svoju ženu.

I love my wife. — accusative 'ženu', the clean -u.

The accusative -u: the one clean accusative

The -a declension accusative singular is -u (ženu, knjigu, vodu) — and it is the cleanest accusative in the whole Croatian noun system, with no animacy split to worry about. Whether the noun is a woman or a book, the accusative is simply -u. (The i-declension is even simpler: its accusative equals the nominative, noć → noć.)

Čitam zanimljivu knjigu.

I'm reading an interesting book. — accusative 'knjigu' (-u).

Cijelu noć nisam spavao.

I didn't sleep all night. — i-declension accusative 'noć' = nominative; note 'cijelu' agrees as feminine -u.

The dative/locative -i and palatalisation (ruka → ruci)

For the -a declension, the dative and locative singular both end in -i (ženi, knjizi). When the stem ends in k, g, h, that front-vowel -i triggers palatalisation — the consonant softens:

Nominative	Dative/Locative	Change
ruka (hand)	ruci	k → c
knjiga (book)	knjizi	g → z
noga (leg)	nozi	g → z
svrha (purpose)	svrsi	h → s
majka (mother)	majci	k → c

This is the k → c, g → z, h → s softening (technically sibilarisation), and it is one of the few places where the -a declension stem itself changes shape. The vowel that causes it is the dative/locative -i, so it strikes exactly in those two cases. Note that the change is to c, z, s here — different from the vocative palatalisation of masculine nouns, which gives č, ž, š.

Dao sam knjigu majci.

I gave the book to mother. — dative 'majci' with k → c.

Imam nešto u ruci.

I have something in my hand. — locative 'ruci' with k → c.

U knjizi piše sve što trebaš znati.

Everything you need to know is in the book. — locative 'knjizi' with g → z.

💡

The k → c, g → z, h → s change in the dative/locative is automatic and obligatory for -a nouns: it is ruci, never *ruki. Memorise the three high-frequency victims — ruka → ruci, noga → nozi, knjiga → knjizi — and the pattern generalises. More on the mechanism at palatalisation in declension.

The vocative: -o vs -e

The -a declension vocative is -o (ženo!, majko!, gospođo!) — a distinctive, slightly emphatic-sounding form. But a subset takes -e instead: most affectionate names and nouns ending in -ica, plus some proper names.

Noun	Vocative	Ending
žena (woman)	ženo!	-o
gospođa (madam)	gospođo!	-o
Maja (name)	Majo!	-o
Mara (name)	Maro!	-o
mama (mum)	mama! (often = nom.)	-a / -o
djevojčica (little girl)	djevojčice!	-e

The i-declension vocative simply equals the genitive/dative form in -i: noći!, ljubavi!

Ženo, daj mi malo mira!

Woman, give me some peace! — vocative -o (sounds blunt/emphatic, used here for effect).

Maro, gdje si bila?

Mara, where have you been? — vocative -o on a feminine name.

The instrumental: -om vs -i/-ju

The -a declension instrumental is -om (ženom, knjigom) — a clean, single ending. The i-declension offers a choice: the regular -i (noći, stvari) or the alternative -ju (noću, ljubavlju), which is common with certain frequent nouns and in fixed expressions.

Razgovarao sam s tom ženom.

I talked with that woman. — instrumental 'ženom' after 's'.

Putujemo noću da izbjegnemo gužvu.

We travel by night to avoid the crowds. — i-declension instrumental 'noću' (the -ju variant).

Plural

Case	žena (-a declension)	noć (i-declension)
Nominativ	žene	noći
Genitiv	žena	noći
Dativ	ženama	noćima
Akuzativ	žene	noći
Vokativ	žene	noći
Lokativ	ženama	noćima
Instrumental	ženama	noćima

The i-declension plural is again almost entirely noći — nominative, genitive, accusative, and vocative all collapse into it — with only the oblique cases (dat/loc/instr) standing out as noćima. The -a declension keeps a distinct genitive plural (see below) but otherwise collapses nom = acc = voc into -e.

Žene su već stigle.

The women have already arrived. — nominative plural 'žene'.

Pričali smo o važnim stvarima.

We talked about important things. — i-declension locative plural 'stvarima'.

The genitive plural: -a vs -i, and the fleeting vowel

The -a declension genitive plural is -a — pronounced with a long vowel (textbooks sometimes mark the length, but in ordinary spelling it is just -a), so žene (gen sg) and žena (gen pl) differ in vowel length, not in spelling. This is the form after numbers from five up and after quantity words.

When a consonant cluster would be hard to pronounce at the end, an -a- slips in — the fleeting vowel (nepostojano a): sestra ("sister") → genitive plural sestara (not sestr); djevojka ("girl") → djevojaka; majka → majki or majka.

The i-declension genitive plural is -i (noći, stvari) — the same -i that runs through most of its paradigm.

Noun	Gen. pl. (-a decl.)	Note
žena	žena (long final vowel)	plain -a
sestra	sestara	fleeting -a- breaks the cluster
djevojka	djevojaka	fleeting -a-
noć (i-decl.)	noći	i-declension -i

Imam pet sestara.

I have five sisters. — genitive plural 'sestara' with the fleeting -a-.

U sobi je bilo puno žena.

There were a lot of women in the room. — genitive plural 'žena' (long final vowel) after 'puno'.

💡

The fleeting -a- is not random: it appears precisely to rescue a genitive plural that would otherwise end in an awkward consonant cluster (sestr-, djevojk-). If you can already pronounce the cluster, no vowel is inserted (žen-a, knjig-a). The rule is covered in full at the fleeting -a-.

How this differs from English

English feminine nouns are not a grammatical category at all — woman and night take the same plural -s and never change for case. Croatian instead routes every feminine noun into one of two declensions whose endings barely overlap, and assigns gender by a mix of ending and tradition that the English ear cannot hear: nothing about noć signals "feminine" to a speaker of a genderless language. The practical consequence is that you must learn each consonant-final feminine as feminine the moment you meet it, because its ending is actively lying to you. The i-declension also has no English analogue at all — there is simply no native intuition for a noun that ends in a consonant yet behaves feminine.

Common Mistakes

❌ Bila je to dug noć.

Incorrect — 'noć' is feminine (i-declension); the adjective must be 'duga', not the masculine 'dug'.

✅ Bila je to duga noć.

It was a long night. — feminine agreement on a consonant-final feminine.

❌ Dao sam knjigu majki.

Incorrect — the dative of 'majka' palatalises k → c: majci, not 'majki'.

✅ Dao sam knjigu majci.

I gave the book to mother. — dative 'majci' (k → c).

❌ Imam pet sestra.

Incorrect — the genitive plural needs the fleeting -a- to break the cluster: sestara.

✅ Imam pet sestara.

I have five sisters. — genitive plural 'sestara'.

❌ Razgovarao sam o stvarama.

Incorrect — 'stvar' is i-declension; its oblique plural is -ima, not the -a-declension -ama: stvarima.

✅ Razgovarao sam o stvarima.

I talked about things. — i-declension locative plural 'stvarima'.

❌ Volim svoja žena.

Incorrect — the accusative singular of an -a feminine is -u: ženu (and the possessive becomes 'svoju').

✅ Volim svoju ženu.

I love my wife. — accusative 'ženu' (-u).

Key Takeaways

There are two feminine declensions: the -a class (žena) and the i-declension of consonant-final feminines (noć). Both are feminine — never read noć as masculine.
The -a class has the clean accusative -u (ženu), the dative/locative -i with k→c, g→z, h→s palatalisation (ruci, knjizi, nozi), the vocative -o (ženo), and the instrumental -om (ženom).
The i-declension is nearly flat: gen/dat/loc/voc all -i (noći), accusative = nominative, instrumental -i or -ju (noći / noću).
Genitive plural: the -a class takes a long -a (žena), with a fleeting -a- to break clusters (sestara); the i-declension takes -i (noći).
The oblique plural is -ama for -a nouns (ženama) but -ima for i-declension nouns (noćima) — do not mix them.
