The noun is where Romanian first surprises an English speaker, because a single English word like house corresponds not to one Romanian word but to a small cluster of facts you have to know together: its gender, how it forms its plural, and how "the" attaches to it. In English a noun is essentially inert — you add -s for the plural, put the in front for definiteness, and you're done. In Romanian a noun comes with a gender that controls agreement, a plural that often reshapes the word from the inside, and a definite article that is glued onto the end rather than placed in front. This page is the map of the whole territory; the dedicated pages drill each piece. The single most important habit to form now is to stop learning nouns as bare words and start learning them as small packages.
Three genders
Every Romanian noun is masculine, feminine, or neuter. Gender is grammatical, not biological: it controls the form of articles, adjectives, numerals, and demonstratives that go with the noun, regardless of whether the thing it names is alive or has a sex. A table is feminine (masă), a train is neuter (tren), and a wine is neuter (vin) — none of which says anything about real-world gender.
| Gender | Example | "a / one" | Typical type |
|---|---|---|---|
| Masculine | băiat (boy), pom (tree) | un | male beings, many trees/objects |
| Feminine | casă (house), floare (flower) | o | female beings, many objects/abstractions |
| Neuter | tren (train), oraș (city) | un | mostly inanimate things |
Am un frate și o soră; el e mai mare, ea e mezina.
I have a brother and a sister; he's older, she's the youngest.
Orașul ăsta are un parc imens și o piață în centru.
This city has a huge park and a square in the centre.
The neuter is the one with no English parallel and no Romance parallel either: it is not a separate set of forms but a noun that behaves like a masculine in the singular and like a feminine in the plural (un tren → două trenuri). That mechanism gets its own treatment; for now just register that there are three categories, not two. Predicting which one a noun belongs to is partly possible from its ending and is the subject of predicting gender from endings.
Number: several plural patterns
Romanian nouns are singular or plural, like English — but they do not form the plural with -s. There is no -s plural anywhere in the language. Instead there are three endings — -i, -e, -uri — chosen largely by gender, and crucially the ending often alters the stem of the word: a vowel shifts, a final consonant softens, or both.
| Singular | Plural | What changed |
|---|---|---|
| băiat (boy) | băieți | ending -i + stem a→ie, t→ț |
| casă (house) | case | ending -e (ă→e) |
| floare (flower) | flori | ending -i + oa→o |
| tren (train) | trenuri | ending -uri |
În parc se jucau mulți copii și câțiva băieți mai mari.
There were many children and a few older boys playing in the park. (copil → copii, băiat → băieți)
Florile din glastră s-au ofilit cât am fost plecată.
The flowers in the vase wilted while I was away. (floare → flori)
This is why the plural is the second thing you must learn with every noun: from the bare singular you often cannot reliably guess it. The full system is laid out in forming plurals: overview.
Definiteness is a suffix, not a front word
This is Romanian's signature feature and the thing most worth absorbing early. Romanian has no standalone word for "the". To make a noun definite, you fasten the article onto its end (it is enclitic). Where English puts a little word in front, Romanian fuses one to the back.
| Indefinite (a / some) | Definite (the) | Meaning |
|---|---|---|
| un băiat | băiatul | a boy / the boy |
| o casă | casa | a house / the house |
| un tren | trenul | a train / the train |
| o floare | floarea | a flower / the flower |
Băiatul de la vecini ne udă florile când plecăm.
The neighbours' boy waters our flowers when we're away. (băiat → băiatul)
Casa de la colț s-a vândut săptămâna trecută.
The house on the corner sold last week. (casă → casa)
Notice in the feminine that the contrast can ride on a single vowel: casă ("a house") vs casa ("the house"). The masculine adds a whole syllable (-ul), the feminine often only swaps -ă for -a. The full endings are on the masculine definite article and feminine definite article pages. The point for the overview is that definiteness changes the shape of the noun itself — another reason a noun is a package, not a fixed string.
Light case marking
Romanian kept more of the Latin case system than its Romance siblings, but far less than German or Russian. In practice nouns show case only lightly:
- Nominative/accusative (subject, direct object) look the same: casa is "the house" whether it is doing the action or receiving it.
- Genitive/dative (possession; indirect object) share one form, which for the definite feminine adds -i: casei ("of/to the house"), fetei ("of/to the girl").
- Vocative (calling someone) has special endings, mostly for people: băiete! ("boy!"), Ioane! ("John!").
Acoperișul casei trebuie reparat înainte de iarnă.
The roof of the house needs repairing before winter. (casei = genitive, 'of the house')
I-am dat fetei cheile de la apartament.
I gave the girl the apartment keys. (fetei = dative, 'to the girl')
For everyday A1 purposes the headline is reassuring: subject and object nouns usually look identical, so you do not decline a noun every time it changes role the way you would in German. The genitive/dative and vocative are real but limited, and they get their own treatment in the cases overview.
Why a noun is a package
Put the four facts together and you see why a Romanian noun cannot be learned as a single word. Scaun ("chair") is: neuter, plural scaune, definite scaunul, definite plural scaunele. Floare ("flower") is: feminine, plural flori, definite floarea. None of the plural, gender, or article behaviour is fully predictable from the bare form, and each one feeds the rest of the grammar — adjectives and numerals must agree in gender and number, so a wrong gender produces a wrong adjective downstream.
Vreau un scaun mai înalt; scaunele astea sunt prea joase.
I want a taller chair; these chairs are too low. (scaun: neuter, sg. înalt → pl. joase)
Common Mistakes
Adding an English-style -s to make a plural:
❌ două casas / două case-uri
Incorrect — there is no -s plural; casă pluralises as case.
✅ două case
two houses
Putting a separate word in front for "the":
❌ la casă / the casă (meaning 'the house')
Incorrect — 'the' is a suffix, not a front word: casa.
✅ casa
the house
Assuming grammatical gender follows biological sex (so 'a thing' must be neuter or 'masculine = male'):
❌ o tren (treating the train as feminine because it's an object)
Incorrect — tren is neuter and patterns like masculine in the singular: un tren.
✅ un tren
a train
Treating the bare and definite feminine as interchangeable (ignoring the ă/a vowel):
❌ Vreau casa. (intending the general 'I want a house / housing')
Wrong sense — casa is definite ('the house'); for 'a house in general' use casă.
✅ Vreau casă.
I want a house / a place to live.
Learning a noun as a single word and inventing its plural later:
❌ un scaun → doi scauni
Incorrect — scaun is neuter (plural scaune, feminine agreement), not masculine scauni.
✅ un scaun → două scaune
one chair → two chairs
Key Takeaways
- A Romanian noun is a package: stem + gender
- plural
- article behaviour. Learn all four at intake.
- plural
- There are three genders (masculine, feminine, neuter); gender is grammatical, not biological.
- The plural uses -i / -e / -uri (no -s ever) and frequently changes the stem — pick the ending, then adjust the stem.
- Definiteness is a suffix: casă → casa, tren → trenul. There is no standalone "the".
- Case marking is light: subject and object look alike; genitive/dative and vocative are limited and learned separately.

- Grammatical Gender: The Three GendersA1 — Romanian has masculine, feminine, and a third gender — the neuter — that English speakers and even speakers of other Romance languages have to build from scratch. Masculine nouns take un and pattern with -i plurals; feminine take o and -ă/-e endings; neuter take un in the singular like a masculine but switch to feminine agreement in the plural (un tren nou / două trenuri noi). Gender is what every adjective, numeral, and article must agree with.
- Predicting Gender from EndingsA2 — Romanian gender is partly readable off the ending. Feminine is the most predictable: -ă and -e usually mean feminine, and the abstract suffixes -tate, -ție, -ură, -eală are almost always feminine. Consonant- and -u-final nouns are the hard cases — they split unpredictably between masculine and neuter, which is exactly why you must memorise their plural (and thus their gender). Heuristics that work, and the cases where they don't.
- Forming Plurals: OverviewA1 — Romanian forms plurals with a tiny set of endings — masculine -i, feminine -e or -i, neuter -uri or -e — but the hard part is the stem alternations those endings trigger (a→e, oa→o, d→z, t→ț). Adding the ending is only half the job; the stem change is the other half.
- The Definite Article: Masculine (-ul, -le)A1 — How the enclitic definite article attaches to masculine and neuter singular nouns — -ul after a consonant, -l after final -u, -le after final -e — and why the choice is phonologically predictable.
- The Definite Article: Feminine (-a, -ua)A1 — How the enclitic definite article attaches to feminine singular nouns — -ă nouns swap to -a (casă → casa), -e nouns add -a (floare → floarea), and stressed-vowel nouns take -ua (cafea → cafeaua) — and why 'a house' and 'the house' differ by only one vowel.
- The Romanian Case System: OverviewA2 — A map of Romanian's surprisingly light case system — five cases that collapse into just two distinct noun forms (Nominative-Accusative and Genitive-Dative) plus a Vocative, with case marked mainly on the article rather than the noun stem.
