The Spanish ordinal for 20th is vigésimo for masculine nouns and vigésima for feminine nouns.
Spanish learners often meet veinte early, then get stuck when English asks for “twentieth.” The short form is easy: vigésimo is the masculine form, and vigésima is the feminine form. The ending changes because Spanish ordinals work like adjectives.
That one detail saves a lot of errors. You don’t say the same form in each spot. You match the word to the noun that follows it, just as you would with primero and primera. Once that pattern clicks, 20th feels less like a memory trick and more like normal Spanish.
What 20th Means In Spanish Grammar
In English, “20th” can act like a neat little label. It can mark rank, order, a chapter, a floor, a lesson, or a birthday date. Spanish splits those jobs more carefully. When you mean order, use the ordinal word vigésimo or vigésima. When you mean a calendar date, Spanish often uses a regular number instead.
That difference matters in class, writing, and conversation. “The twentieth lesson” is about order, so Spanish uses la vigésima lección. “The twentieth of June” is a date, so everyday Spanish says el veinte de junio. English uses “twentieth” in both places, but Spanish does not copy that pattern.
Masculine And Feminine Forms
Vigésimo pairs with masculine nouns. Say el vigésimo capítulo for “the twentieth chapter” and el vigésimo piso for “the twentieth floor.” The article and ending both point to a masculine noun.
Vigésima pairs with feminine nouns. Say la vigésima página for “the twentieth page” and la vigésima pregunta for “the twentieth question.” The ending is not decoration. It carries grammar, so treat it as part of the word you need.
Why Twentieth Changes Ending
Spanish ordinals act like describing words. They sit next to a noun and agree with it. That is why you see vigésimo, vigésima, and their plural forms vigésimos and vigésimas. The form you choose depends on gender and number.
Most beginner mistakes come from translating the English ending “-th” too directly. Spanish does not add one fixed suffix to veinte. It uses a separate ordinal family. The spelling also carries an accent: vigésimo. Leave off the accent in casual notes and people may still understand you, but clean writing includes it.
How To Say 20Th In Spanish With Nouns And Dates
The safest question to ask is this: are you naming order, or are you naming a date? If it is order, pick the ordinal. If it is a date after the first day of the month, pick the regular number. This rule keeps your Spanish clear without stuffing extra grammar into each sentence.
For a school task, a quiz answer, or a study sheet, write the full form when you can. Abbreviations exist, such as 20.º and 20.ª, but learners gain more from spelling the word. Full words also make gender agreement easier to see.
A Simple Way To Choose The Form
Start with the noun, not the English number. If the noun is libro, capítulo, piso, or lugar, the ending usually becomes -o. If the noun is página, pregunta, lección, or unidad, the ending usually becomes -a.
Then check whether the noun is singular or plural. One twentieth page is la vigésima página. Several twentieth pages in different books could be las vigésimas páginas. The phrase sounds formal in some plural cases, but the grammar still follows the noun.
Dates work differently. In Spanish, April twentieth is el veinte de abril, not el vigésimo de abril in ordinary speech. That single split between order and date is the part that helps learners avoid the most awkward translations.
| English Meaning | Spanish Form | Why It Fits |
|---|---|---|
| 20th chapter | el vigésimo capítulo | Capítulo is masculine singular |
| 20th page | la vigésima página | Página is feminine singular |
| 20th question | la vigésima pregunta | Pregunta is feminine singular |
| 20th floor | el vigésimo piso | Piso is masculine singular |
| 20th lesson | la vigésima lección | Lección is feminine singular |
| 20th place in a race | el vigésimo lugar | Lugar is masculine singular |
| 20th editions | las vigésimas ediciones | Plural feminine noun needs plural ending |
| 20th birthdays as events | los vigésimos cumpleaños | Plural masculine noun needs plural ending |
Pronunciation That Feels Natural
Say vigésimo in four smooth beats: vee-HEH-see-moh. The stress lands on the syllable with the accent mark. Say vigésima the same way, but close with “mah” instead of “moh.”
The letter g before é has an English “h” sound in many accents, close to heh. The middle s stays soft and clear. Don’t turn the word into “vee-JEH-see-moh” unless you’re copying a local accent that uses that sound.
Common Mistakes With The Spanish Word For 20th
A common slip is writing veinteavo when the meaning is ordinal order. Veinteavo can refer to a fractional idea, like one twentieth, in some contexts. It is not the clean choice for “the twentieth chapter” or “the twentieth lesson.” Use vigésimo or vigésima for rank and sequence.
Another slip is using the ordinal for each date. English says “June twentieth,” but Spanish date phrasing uses veinte: el veinte de junio. The first day of the month is the main special case: el primero de mayo. After that, cardinal numbers are the normal path for dates.
Accent Marks And Abbreviations
The accent in vigésimo and vigésima tells readers where the stress falls. In polished Spanish, the mark belongs there. It is small, but it keeps the spelling correct and trains your mouth to stress the right syllable.
Ordinal abbreviations use a tiny raised ending in formal writing: 20.º for masculine and 20.ª for feminine. You may also see 20.o or 20.a when superscript is not available. In learner writing, full words are usually clearer.
| Situation | Better Spanish | Skip This Error |
|---|---|---|
| Calendar date | el veinte de abril | el vigésimo de abril |
| Class rank | el vigésimo alumno | el veinte alumno |
| Feminine noun | la vigésima unidad | la vigésimo unidad |
| Plural feminine noun | las vigésimas filas | las vigésima filas |
| Ordinal abbreviation | 20.º piso | 20th piso |
When To Use Vigésimo Instead Of Veinte
Use vigésimo when “twentieth” answers “which one in the order?” It names sequence. A textbook chapter, a contest place, a page, a unit, a floor, or a numbered lesson can all take the ordinal if the noun has that ordered sense.
Use veinte when “twenty” answers “how many?” or names a date. Veinte estudiantes means twenty students, not twentieth student. El veinte de marzo means March 20. The number is not ranking anything there.
Clean Study Sentences
Try reading these pairs out loud. Estoy en la vigésima página means “I’m on the twentieth page.” La clase es el veinte de enero means “The class is on January twentieth.” The English version uses “twentieth” twice, but Spanish chooses two different number words.
Here is another pair. Es el vigésimo capítulo means “It is the twentieth chapter.” El capítulo tiene veinte páginas means “The chapter has twenty pages.” One sentence ranks the chapter; the other counts the pages.
Practice Pattern For Twentieth In Spanish
A simple drill works well: pick a noun, check its gender, then choose the ending. Say capítulo, then el capítulo, then el vigésimo capítulo. Say unidad, then la unidad, then la vigésima unidad.
Next, switch to plural nouns. Los vigésimos capítulos and las vigésimas unidades train your ear to hear the final -s. This helps when reading school material, writing labels, or answering grammar drills.
Mini Drill For Better Recall
Write four nouns on a page: capítulo, página, unidad, and piso. Add the right article before each one. Then add the matching form of 20th. You should get el vigésimo capítulo, la vigésima página, la vigésima unidad, and el vigésimo piso.
Now add one date line: el veinte de mayo. Seeing the date form next to the rank forms trains your eye to separate them. That small contrast builds accuracy faster than memorizing a lone word.
A Final Check Before You Write It
Ask three short questions before you write the word. Is this a rank or a date? Is the noun masculine or feminine? Is the noun singular or plural? Your answer gives you the right form.
If you mean rank with a masculine singular noun, write vigésimo. If you mean rank with a feminine singular noun, write vigésima. If you mean a date like April 20, write veinte. That small choice makes the whole phrase read like natural Spanish.
