Illustration for Mastering “Fifteen” in Spanish: A Comprehensive Guide

“Fifteen” in Spanish

Spanish Vocabulary 16 min read Updated 9 October 2026

Fifteen in Spanish is quince, pronounced KEEN-seh in Latin America and KEEN-theh in most of Spain. It never changes form: quince libros, quince casas. You will hear it in ages (tengo quince años), times (las tres y quince, or las tres y cuarto), dates (el 15 de mayo) and in quince días, the usual way to say “two weeks”.

Neighbouring numbers: 14 (catorce), 16 (dieciséis); see also Spanish ordinal numbers and how to say the date in Spanish.

  • Definition of “Quince”

    In Spanish, the number fifteen is represented by the word “quince.” It is a cardinal number, meaning it’s used for counting or indicating quantity. The word “quince” is invariable, meaning it doesn’t change its form based on gender or number (singular or plural). However, its usage can vary depending on the context in which it’s used.

    As a cardinal number, “quince” functions primarily as an adjective when modifying a noun, although it often appears without a noun if the context is clear. For instance, you can say “Tengo quince manzanas” (I have fifteen apples) or simply “Tengo quince” (I have fifteen), if it’s understood that you are referring to apples.

    The word “quince” also plays a vital role in expressing age, time, dates, and measurements in Spanish. Its correct usage is essential for clear and accurate communication.

    Structural Breakdown

    The word “quince” does not have a structural breakdown in the same way as larger numbers in Spanish, which are formed by combining tens and units (e.g., veintiuno – twenty-one). It is a standalone word with its own unique spelling and pronunciation.

    However, understanding the formation of numbers in Spanish can provide a broader context. Numbers 11 through 15 (once, doce, trece, catorce, quince) have unique names. From 16 onwards, the numbers are formed by combining “diez” (ten) with the units: dieciséis (sixteen), diecisiete (seventeen), and so on. Understanding this pattern helps learners grasp the overall structure of the Spanish number system.

    The spelling of “quince” is straightforward and consistent. It consists of six letters: q-u-i-n-c-e. The only trap is the silent u: in qu it is not pronounced, so quince sounds like “keen-“, never “kween-“. Learners sometimes write it as they hear it (*quinse, *kinse), but the spelling is always quince.

    Pronunciation of “Quince”

    The pronunciation of “quince” is relatively straightforward for English speakers. Here’s a breakdown:

    • “Qui” is pronounced like “kee.” The “q” in Spanish is always followed by a “u,” and the combination “qu” is pronounced like the English “k.”
    • “nce” is pronounced like “n-theh” (with a soft “th” sound as in “thin” in many parts of Spain, and like “n-seh” in Latin America).

    Therefore, “quince” is pronounced as “keen-theh” (Spain) or “keen-seh” (Latin America). It’s important to note the regional variations in the pronunciation of the “c” before “e” or “i.”

    To improve your pronunciation, try listening to native Spanish speakers pronounce the word and mimic their intonation and rhythm. Online resources like Forvo and YouTube can provide audio examples.

    Grammatical Gender and Agreement

    Unlike many nouns in Spanish, the number “quince” does not have a grammatical gender. It is invariable and does not change its form to agree with masculine or feminine nouns. However, the nouns it modifies will still have gender and require agreement with other adjectives and articles.

    For example:

    • Quince chicos (Fifteen boys) – “chicos” is masculine plural.
    • Quince chicas (Fifteen girls) – “chicas” is feminine plural.

    In both cases, “quince” remains the same, but the nouns “chicos” and “chicas” reflect the gender of the people being counted. Adjectives describing those nouns would also need to agree in gender and number.

    The absence of grammatical gender for numbers simplifies their usage, as you don’t need to worry about matching the number to the gender of the noun it modifies. This holds for most cardinal numbers, with two exceptions: uno (and numbers ending in it) becomes un/una (veintiuna casas), and the hundreds agree (doscientas personas).

    Cardinal vs. Ordinal Numbers

    It’s essential to distinguish between cardinal and ordinal numbers. Cardinal numbers (like “quince”) indicate quantity, while ordinal numbers indicate position in a sequence (e.g., first, second, third). The ordinal number corresponding to “quince” is “decimoquinto” (fifteenth). However, ordinals above tenth sound formal in everyday Spanish, so speakers usually put the cardinal number after the noun instead: el piso quince (the fifteenth floor), el capítulo quince (chapter fifteen).

    Here’s a comparison:

    Type Number Spanish Usage
    Cardinal 15 Quince Indicates quantity (e.g., fifteen apples)
    Ordinal 15th Decimoquinto/a Indicates position in a sequence (e.g., the fifteenth day)

    While “quince” is used to count things, “decimoquinto” is used to specify the position in a numbered sequence. For example: “El decimoquinto día del mes” (The fifteenth day of the month).

    Note that quinto/a means “fifth”, not “fifteenth”. In speech, the cardinal after the noun replaces decimoquinto/a. For example, “La página quince” (Page fifteen) is more common than “La página decimoquinta“.

    Examples of “Quince” in Sentences

    To fully understand the usage of “quince,” let’s explore various examples in different contexts.

    Age

    “Quince” is frequently used to express age, particularly the age of fifteen. The phrase “quince años” (fifteen years) is commonly used, and the celebration of a girl’s fifteenth birthday, known as a “quinceañera,” is a significant cultural event in many Latin American countries.

    Usage Rules

    The usage rules for “quince” are relatively simple, as it is an invariable cardinal number. Here are the key rules to remember:

    • Invariability: “Quince” does not change its form based on gender or number.
    • Placement: “Quince” typically precedes the noun it modifies (e.g., quince libros).
    • Context: The meaning of “quince” depends on the context. It can refer to age, time, quantity, dates, or measurements.
    • Clarity: Ensure the context is clear when using “quince” without a noun. For example, if you say “Tengo quince,” it should be clear what you have fifteen of.

    There are no significant exceptions to these rules. However, it’s important to be aware of regional variations in pronunciation and idiomatic expressions that may involve the number “quince.”

    Common Mistakes

    While “quince” is a straightforward number, learners sometimes make common mistakes. Here are a few to watch out for:

    Incorrect Correct Explanation
    *Quinces libros Quince libros “Quince” is invariable and does not become plural.
    *Tengo quince años viejos. Tengo quince años. The word “viejos” (old) is unnecessary when expressing age.
    *Soy quince años. Tengo quince años. Age uses tener (“to have”), not ser or estar.
    *Diez y cinco / *diecicinco Quince 11 to 15 have their own names (once, doce, trece, catorce, quince); the dieci- pattern starts at 16.

    Avoiding these common mistakes will help you use “quince” more accurately and confidently.

    Quince Días, Quincena and Other Expressions

    Where English counts two weeks as fourteen days, Spanish usually says fifteen (counting both ends), and this gives a small family of everyday words:

    • quince días: two weeks, a fortnight. Vuelvo dentro de quince días. (I’ll be back in two weeks.)
    • cada quince días: every two weeks. Vamos al cine cada quince días.
    • la quincena: half a month (the 1st to the 15th, or the 16th to the end), and in many countries a half-monthly pay period. Me pagan por quincena. (I get paid twice a month.)
    • quincenal: fortnightly, twice-monthly. una revista quincenal.
    • los quince or la fiesta de quince: a girl’s fifteenth-birthday celebration; the girl herself is the quinceañera. Mi prima celebra sus quince en junio.

    Regional Variations

    The pronunciation of “quince” can vary slightly depending on the region. In Spain, the “c” before “e” is typically pronounced with a “th” sound, while in Latin America, it’s pronounced like an “s.” These variations are minor and don’t affect the meaning of the word, but it’s helpful to be aware of them.

    Additionally, some regions may have unique slang or colloquial expressions that involve numbers. While “quince” itself may not be part of these expressions, understanding the broader context of regional language use can enhance your overall fluency.
