Romanian ordinal numbers

Romanian ordinal numbers show position in a sequence: primul (first), al doilea (second), and a treia (third). They behave like agreeing words, so the form follows the grammatical gender of the noun: al doilea capitol (the second chapter), but a doua lecție (the second lesson).

How do you choose an ordinal form?

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

How are ordinals formed after ten?

From second onward, Romanian normally frames the cardinal 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, a feminine noun takes the feminine form, and a neuter noun follows the masculine pattern in the singular: al treilea student (the third student), a treia stație (the third station), and al treilea exercițiu (the third exercise). This follows the wider Romanian noun gender pattern.

What are the two common forms 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.

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

In the basic nominative-accusative patterns, cel de-al doilea and cea de-a doua have the same meaning as al doilea and a doua. They are especially useful when the ordinal stands alone or when a more visibly articulated phrase is needed: Cel de-al treilea a răspuns corect. (The third one answered correctly.) In genitive-dative phrases, 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.

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).

• Use the ordinal as a noun substitute when the noun is understood: Sportivul a ieșit al doilea. (The athlete finished second.)
• Use ordinal phrases with dată or oară for repeated events: a doua oară (the second time) and a treia dată (the third time).
• With parte, position changes the meaning: a treia parte means one third, while partea a treia means the third part.
• For book, film, or performance sections, careful written Romanian uses forms such as capitolul al doilea (the second chapter) and volumul întâi (the first volume).

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.
• Do not copy the conversational cardinal shortcut into formal writing when the ordinal form is expected: prefer capitolul al treilea to capitolul trei in a careful text.
