Romanian ordinal numbers

Romanian ordinal numbers show position in a sequence: primul (first), al doilea (second), and a treia (third). Ordinal forms agree with the noun’s grammatical gender: al doilea capitol (the second chapter), but a doua lecție (the second lesson). The core patterns cover singular noun phrases. The later case example supports recognition rather than providing a full plural or case paradigm.

How do you choose an ordinal form?

Choose the masculine-pattern form with a masculine or neuter singular noun. Choose the feminine form with a feminine noun. For first, learn the separate pair primul/prima and recognize întâiul/întâia.

How are Romanian ordinal numbers formed?

From second onward, Romanian normally frames the cardinal number with al ... -lea for the masculine pattern or a ... -a for the feminine pattern. In a compound ordinal, only the final number becomes ordinal: al douăzeci și doilea (the twenty-second) and a douăzeci și doua (the twenty-second).

• If the cardinal ends in a vowel, the feminine ending replaces that final vowel: două becomes a doua, nouă becomes a noua, and patru becomes a patra.
• After a final consonant, the masculine form commonly inserts -u- before -lea: opt becomes al optulea and milion becomes al milionulea.
• Some stems change spelling in the derived form: cinci becomes cincea and douăzeci becomes douăzecea. Learn these common forms as whole words.
• For a compound number, keep the earlier cardinals unchanged and make only the last one ordinal: al o sută douăzeci și treilea (the 123rd), a o sută douăzeci și treia (the 123rd).

How does gender agreement work in a sentence?

The noun controls the ordinal form, not the real-world sex of its referent. A masculine noun takes the masculine-pattern form: al treilea student (the third student). A feminine noun takes the feminine form: a treia stație (the third station). A neuter noun follows the masculine pattern in the singular: al treilea exercițiu (the third exercise). These forms follow the wider Romanian noun gender pattern.

When do you use primul or întâiul for first?

Use primul and prima as the ordinary forms for first: primul examen (the first exam) and prima zi (the first day). Întâiul and întâia are also standard, but they do not replace primul and prima in every fixed expression. In particular, clasa întâi means first grade, while prima clasă means the first classroom or class in a sequence.

Where does the ordinal go?

Before a noun, an ordinal normally comes before the noun and the noun is not definite: a treia încercare (the third attempt). After a noun, the noun is normally definite: partea a treia (the third part). In expressions for floors, grades, years, rows, and similar labels, postposed ordinals are common: etajul întâi (the first floor) and anul al treilea (the third year).

• An ordinal can replace an understood noun: Sportivul a ieșit al doilea. (The athlete finished second.)
• Ordinal phrases with dată or oară identify which repetition is meant: a doua oară (the second time) and a treia dată (the third time).
• Ordinal position changes the meaning with parte: a treia parte means one third, while partea a treia means the third part.
• Careful written Romanian uses ordinal forms for book, film, or performance sections: capitolul al doilea (the second chapter) and volumul întâi (the first volume).

When do you see cel de-al or cea de-a?

In basic nominative-accusative patterns—the forms used here for subjects and direct objects—cel de-al doilea and cea de-a doua have the same meaning as al doilea and a doua. The longer forms can stand alone: Cel de-al treilea a răspuns corect. (The third one answered correctly.) In genitive-dative phrases—phrases that can mark possession or an indirect object—the support word changes: I-am dat cartea celui de-al treilea student. (I gave the book to the third student.) For first, the parallel form is cel dintâi or cea dintâi.

Can a cardinal replace an ordinal?

In colloquial speech, speakers often use a cardinal in labels for sections, especially with words such as capitol, volum, or act: capitolul doi can be heard for the second chapter. In neutral careful writing, use the ordinal pattern capitolul al doilea. Do not extend this conversational shortcut to every ordinal phrase.

Mistakes to avoid

• Do not use the masculine form with every noun: say a doua lecție, not al doilea lecție.
• Do not build first as al unulea. Use primul or întâiul for masculine or neuter singular and prima or întâia for feminine singular.
• Do not make every part of a compound ordinal ordinal: 22nd is al douăzeci și doilea, not al douăzeci și al doilea.
• Do not confuse clasa întâi (first grade) with prima clasă (the first classroom or class in a sequence).
• Do not treat cel de-al doilea as a different rank from al doilea. In basic nominative-accusative use, both mean second. The longer form also helps carry case in phrases such as celui de-al doilea.
• In careful writing, prefer capitolul al treilea to the conversational form capitolul trei.
