The most direct translation for fourth in Spanish is cuarto when used as a masculine adjective and cuarta when used as a feminine adjective. On the flip side, like many aspects of the Spanish language, the context determines the exact form you need. Whether you are talking about dates, fractions, floors in a building, or rankings in a competition, the word shifts slightly to fit the grammatical gender and the specific grammatical role it plays in the sentence Easy to understand, harder to ignore..
Understanding these nuances is essential for moving beyond basic vocabulary into fluent, natural communication. This guide breaks down every way to express "fourth" in Spanish, complete with pronunciation tips, grammatical rules, and real-world examples It's one of those things that adds up..
The Basics: Cuarto vs. Cuarta
Spanish is a gendered language. Every noun is classified as either masculine or feminine, and adjectives must agree with the noun they modify. Since ordinal numbers function as adjectives, "fourth" changes its ending based on the noun it describes.
- Cuarto (pronounced KWAR-toh): Used with masculine nouns.
- El cuarto piso (The fourth floor).
- El cuarto capítulo (The fourth chapter).
- Cuarta (pronounced KWAR-tah): Used with feminine nouns.
- La cuarta vez (The fourth time).
- La cuarta calle (The fourth street).
Pro Tip: If you are using the ordinal number as a pronoun (standing alone without a noun immediately following), you generally use the masculine form cuarto as the default, or match the gender of the implied noun Simple, but easy to overlook..
- ¿Cuál prefieres? El cuarto. (Which do you prefer? The fourth one [masculine object implied]).
- Esta es la cuarta. (This is the fourth one [feminine object implied]).
The Apocope Rule: Dropping the 'O'
A unique grammatical feature in Spanish affects the ordinal numbers first (primero) and third (tercero), but it also applies to cuarto when it precedes a masculine singular noun. This is called apócope (apocope) That's the whole idea..
When cuarto comes immediately before a masculine singular noun, it drops the final -o and becomes cuart.
- Standard: El cuarto libro (The fourth book) — Wait, this is incorrect in standard grammar for "cuarto".
Correction/Clarification: Unlike primero -> primer and tercero -> tercer, the Royal Spanish Academy (RAE) dictates that cuarto does NOT typically undergo apocope in modern standard Spanish. You say el cuarto piso, not el cuart piso.
However, in some regional dialects or older texts, you might encounter cuart, but learners should stick to cuarto before masculine nouns to sound correct and natural That alone is useful..
Ordinal Numbers vs. Cardinal Numbers
A common mistake for English speakers is confusing ordinal numbers (order: 1st, 2nd, 3rd, 4th) with cardinal numbers (quantity: 1, 2, 3, 4).
- Cardinal (Quantity): Cuatro (Four). Used for counting. Tengo cuatro manzanas (I have four apples).
- Ordinal (Order): Cuarto / Cuarta (Fourth). Used for ranking or sequence. Llegué en cuarto lugar (I arrived in fourth place).
Critical Distinction for Dates: In English, we say "July Fourth" (ordinal). In Spanish, dates typically use cardinal numbers (except for the first of the month) Small thing, real impact..
- El cuatro de julio (July 4th / The four of July).
- El primero de enero (January 1st — only exception where ordinal is standard).
If you say el cuarto de julio, a native speaker might understand you, but it sounds like "the fourth [item] of July" rather than the calendar date.
Common Contexts and Specific Usages
1. Floors and Building Levels
This is one of the most practical uses for travelers and residents. In many Spanish-speaking countries, the "ground floor" is la planta baja or el primer piso. What Americans call the "second floor" is often el primer piso (first floor) in Spain and parts of Latin America. Because of this, the "fourth floor" can get confusing.
- Spain/Mexico (Common): Ground floor = Planta baja. 1st up = Primero. 2nd up = Segundo. 3rd up = Tercero. 4th up = Cuarto.
- USA/Other regions: Ground floor = Primer piso. 4th floor = Cuarto piso.
Always clarify: ¿El cuarto piso contando desde la planta baja? (The fourth floor counting from the ground floor?).
2. Fractions and Mathematics
When expressing fractions (1/4), the word changes entirely. It is no longer an ordinal adjective but a noun representing a part of a whole And that's really what it comes down to..
- Un cuarto (One fourth / One quarter).
- Tres cuartos (Three fourths / Three quarters).
- Un cuarto de hora (A quarter of an hour / 15 minutes).
- Un cuarto de kilo (A quarter kilo / 250 grams).
Note: Cuarto here is a masculine noun, so it doesn't change for gender (una cuarta refers to a span/measurement, not the fraction 1/4) Simple, but easy to overlook..
3. Sports, Rankings, and Competitions
When discussing placement in a race, tournament, or chart position, you use the ordinal forms.
- Quedó en cuarto lugar. (He/She placed in fourth place).
- El equipo terminó cuarto en la liga. (The team finished fourth in the league).
- Es su cuarta victoria. (It is his/her fourth victory — victoria is feminine).
4. Kings, Popes, and Royalty (Roman Numerals)
For monarchs and popes, Spanish uses Roman numerals but reads them as ordinal numbers. The convention is to use the ordinal number after the name.
- Felipe Cuarto (Philip IV).
- Juan Pablo Segundo (John Paul II).
- Enrique Octavo (Henry VIII).
For the "Fourth," you always use the masculine Cuarto regardless of the person's gender (though historically monarchs are male, the title grammar remains masculine). Isabel Cuarta would be incorrect; it would be Isabel IV (Isabel Cuarta) if a queen were the fourth, but usually, the numeral is read with the masculine ordinal for the title Rey (King) implied, or feminine Reina Cuarta. Standard practice: Isabel Cuarta (Queen Elizabeth the Fourth - hypothetical) Small thing, real impact..
Not the most exciting part, but easily the most useful.
5. The "Fourth" as a Noun: El Cuarto
El cuarto functions as a noun meaning "the room" or "the bedroom." This is a false friend situation for the concept of "fourth."
- Voy a mi cuarto. (I am going to my room).
- El cuarto de baño. (The bathroom).
Context is king here. If someone says el cuarto, they almost always mean "the room." If they mean "the fourth one," they usually say el cuarto only if the context of a list or sequence is already established.
