Indefinite Articles in Romanian

In Brief

Romanian places its indefinite articles before the noun: un with a masculine or neuter singular noun, o with a feminine singular noun, and niște with plural nouns of any gender. Thus, un om means “a man,” o casă means “a house,” and niște cărți means “some books.”

Overview

An indefinite article introduces a person or thing without identifying one specific example: English a/an in “a chair,” or some in “some books.” In Romanian, choosing the article depends on the noun’s gender (its grammatical class) and number (singular or plural). This makes indefinite articles one of the first practical uses of Romanian noun gender at A1 level.

The beginner rule is compact: learn un, o, and niște. The article stands before the noun, unlike the Romanian definite article—the equivalent of English the—which is normally attached to the end of the noun. Compare o casă (“a house”) with casa (“the house”).

Romanian has masculine, feminine, and neuter nouns. A neuter noun behaves like a masculine noun in the singular, so it takes un: un scaun (“a chair”). In the plural, niște works with all three genders. Knowing a noun together with its singular article is therefore an efficient way to learn its gender.

How It Works

The core forms

Gender and number	Article	Romanian example	English meaning
Masculine singular	un	un om	a man
Feminine singular	o	o casă	a house
Neuter singular	un	un scaun	a chair
Plural, any gender	niște	niște cărți	some books

The basic pattern is:

article + noun (+ adjective)

un băiat înalt — a tall boy
o fată înaltă — a tall girl
un hotel modern — a modern hotel
niște hoteluri moderne — some modern hotels

An adjective (a word that describes a noun, such as “tall” or “modern”) usually follows the noun and agrees with it in gender and number. The article does not change merely because an adjective is present.

Masculine singular: un

Use un before a masculine singular noun:

un bărbat — a man
un câine — a dog
un student — a male student
un prieten — a friend (male, or grammatically masculine)

The ending of a noun can offer clues to its gender, but it is not always reliable. Learn the article as part of the vocabulary item: not just câine, but un câine.

Feminine singular: o

Use o before a feminine singular noun:

o femeie — a woman
o carte — a book
o zi — a day
o universitate — a university

English chooses a or an according to the following sound. Romanian does not make that distinction. O remains o, whether the next word starts with a consonant or a vowel: o casă, o idee, o oră.

Neuter singular: un

Romanian neuter nouns take the masculine pattern in the singular and the feminine pattern in the plural. For the indefinite article, the important A1 rule is that a singular neuter noun takes un:

un scaun — a chair
un oraș — a city
un hotel — a hotel
un exercițiu — an exercise

The form un alone does not tell you whether a noun is masculine or neuter. Its plural pattern often reveals the difference, which is why it helps to learn singular and plural together: un scaun — niște scaune.

Plural: niște

Use niște before indefinite plural nouns of any gender when the meaning is “some” or “a number of”:

niște băieți — some boys
niște fete — some girls
niște cărți — some books
niște scaune — some chairs

Unlike English a/an, Romanian therefore has an overt plural indefinite article. However, niște is not compulsory every time English has a bare plural. A noun can appear without it when speaking generally or when the exact quantity is not being highlighted:

Cumpăr cărți. — I buy books / I am buying books.
Cumpăr niște cărți. — I am buying some books.

The second sentence presents a particular, unspecified set of books. The first is more neutral and can also describe a general activity, depending on context.

Niște with uncountable nouns

Niște can also mean “some” with a mass or uncountable noun—a substance or material not normally counted as separate items:

niște apă — some water
niște pâine — some bread
niște cafea — some coffee

Here the noun is singular in form, but niște expresses an unspecified quantity. This useful pattern goes beyond the simplest “plural article” rule.

Article or number?

Un and o can also be the numeral “one.” Context and emphasis usually show the intended meaning:

Am cumpărat o carte. — I bought a book.
Am cumpărat o carte, nu două. — I bought one book, not two.

In ordinary speech, stronger stress often falls on un/o when the exact number matters. The spelling does not change.

Examples in Context

Romanian	English	Note
Am văzut un om în parc.	I saw a man in the park.	Masculine singular
Ea locuiește într-o casă veche.	She lives in an old house.	Feminine singular; într-o combines în with o
Cumpăr un scaun pentru birou.	I am buying a chair for the office.	Neuter singular takes un
Pe masă este o carte.	There is a book on the table.	A new, unidentified item
Avem un hotel aproape de gară.	We have a hotel near the station.	Neuter singular
În clasă sunt niște studenți.	There are some students in the classroom.	Masculine plural
Maria cumpără niște flori.	Maria is buying some flowers.	Feminine plural
Avem nevoie de niște pahare.	We need some glasses.	Neuter plural
Vrei niște apă?	Would you like some water?	Unspecified amount of a substance
El este un profesor bun.	He is a good teacher.	Article + noun + adjective
Caut o idee simplă.	I am looking for a simple idea.	Feminine agreement
Am cumpărat o carte, nu două.	I bought one book, not two.	O functions as the number “one”

Notice într-o in the second example. Before an indefinite article, the preposition în (“in”) commonly appears in the combined forms într-un and într-o: într-un oraș (“in a city”), într-o casă (“in a house”). These are written with a hyphen.

Common Mistakes

1. Using o with every noun whose English equivalent takes “a”

Wrong: o scaun
Right: un scaun
Why: Scaun is neuter. Neuter nouns follow the masculine pattern in the singular and take un.

2. Treating neuter singular nouns as a separate article class

Wrong: trying to find a special neuter singular article
Right: un hotel, un oraș, un exercițiu
Why: Romanian has a neuter gender, but no separate basic neuter indefinite article. Use un in the singular.

3. Changing the article according to the noun’s first sound

Wrong: avoiding o before a vowel, by analogy with English a/an
Right: o idee, o oră, o adresă
Why: Romanian article choice follows gender, not whether the next word begins with a vowel.

4. Using a singular article with a plural noun

Wrong: un cărți or o fete
Right: niște cărți, niște fete
Why: Un and o are singular. Niște is the plural form for every gender.

5. Adding an article to a profession automatically

Awkward in a neutral statement: Sunt un profesor.
Usual: Sunt profesor. — I am a teacher.
With a description: Sunt un profesor răbdător. — I am a patient teacher.
Why: After a fi (“to be”), Romanian often uses a bare profession or role when simply stating what someone is. An article becomes natural when the noun phrase is described, classified, or emphasized.

6. Using niște for every English plural noun

Over-specific: Citesc niște cărți when you mean “I read books” as a general habit.
Better: Citesc cărți.
Why: Niște points to an unspecified but contextually relevant quantity. A bare plural is often better for a general category or habit.

Usage Notes

Introducing new information

Indefinite articles commonly introduce something for the first time. Once it is identifiable, Romanian often switches to the definite article:

Am văzut un câine. Câinele era foarte prietenos.
I saw a dog. The dog was very friendly.

This resembles English discourse, but the Romanian definite article is usually attached to the noun: câinele, not a separate word before it.

Natural placement

The neutral order is article + noun + adjective: o casă frumoasă. Some common adjectives can stand between the article and noun, especially when they carry a conventional or expressive meaning: un bun prieten (“a good friend”), o altă zi (“another day”). At beginner level, noun + adjective is the safest general pattern, but fixed phrases should be learned as you meet them.

Niște is more than a mechanical plural

Depending on context, niște may sound like “some,” “a few,” or simply an indefinite set. It does not state an exact number. If quantity matters, use a numeral or quantity expression instead: două cărți (“two books”), câteva cărți (“a few books”).

Beyond the Basics / Advanced Use

You do not need to master the following forms at A1, but they complete the article system and will appear in ordinary Romanian.

Genitive and dative forms

Romanian marks case, meaning that a noun phrase can change form according to its role in the sentence. The genitive often expresses possession (“of”), while the dative commonly marks a recipient (“to/for someone”). The singular indefinite articles become unui for masculine and neuter nouns and unei for feminine nouns. The plural form is unor for all genders.

Gender and number	Basic form	Genitive/dative form	Example	Meaning
Masculine singular	un	unui	cartea unui student	a student’s book / the book of a student
Feminine singular	o	unei	cartea unei studente	a female student’s book
Neuter singular	un	unui	ușa unui hotel	a hotel’s door / the door of a hotel
Plural, any gender	niște	unor	le dau unor prieteni	I give [it] to some friends

The noun—and any adjective attached to it—may also take a case form: unei case vechi (“of/to an old house”). Treat the whole noun phrase as a unit rather than changing only the article.

Forms after prepositions

Most common prepositions use the same article forms as the basic pattern: cu un prieten (“with a friend”), pentru o colegă (“for a colleague”). Some combinations have special written forms:

într-un magazin — in a shop
într-o cameră — in a room
dintr-un oraș — from a city
dintr-o țară — from a country

The final -r- belongs to these established combinations, and the hyphen is required.

Negative counterparts

To mean “no” or “not any” before a singular noun, Romanian commonly uses niciun (masculine/neuter) and nicio (feminine): Nu am niciun mesaj (“I have no messages / I do not have any message”), Nu am nicio întrebare (“I have no questions”). In their ordinary adjectival use, these forms are written as one word. They belong to negation rather than to the basic affirmative indefinite-article pattern.

Stylistic force of niște

With an adjective or a strongly evaluative noun, niște can sometimes carry an expressive tone, not merely neutral quantity. The exact effect depends heavily on context and intonation. As a learner, first use it neutrally for “some”; learn expressive uses from complete phrases rather than trying to reproduce them from a rule.

Practice Tips

Learn nouns with two clues. Record un scaun — scaune or o carte — cărți, not just the dictionary form. The article trains gender, while the plural helps you recognize neuter nouns.
Sort everyday objects aloud. Look around a room and make three groups: un telefon, o masă, un scaun. Then turn them into plural phrases with niște.
Practice the information chain. Write pairs such as Am o carte. Cartea este interesantă. This builds the useful contrast between introducing “a book” and referring back to “the book.”
