Spanish Words That Start With U: 30 Everyday Terms
🇪🇸 Spanish · 30 cards · A2 · by Lucía Herrera
The letter U is a small corner of the dictionary, but plenty of high-frequency words live there: uno, usted, usar, último, útil. This list comes straight from my tutoring notebook, so it's the U-words my students actually need, not obscure entries.
Two things cause trouble. First, the uno / un / unos / único family looks repetitive, but each item behaves differently in a sentence. Second, pairs like usar / utilizar and urgente / urgencia feel interchangeable and aren't quite — read those notes before you drill. And say the examples out loud: Spanish u is a plain "oo" (útil = OO-teel), never the English "yoo" — though it falls silent in que, qui, gue, gui.

| # | Spanish | English | Example | Audio |
|---|---|---|---|---|
| 1 | uno Stands alone as the numeral (tengo uno). Right before a masculine singular noun it shortens to 'un' (un libro); the feminine form is 'una' (una casa). | one | Solo me queda uno, ¿lo quieres? I've only got one left, do you want it? | |
| 2 | un Masculine singular indefinite article; feminine is 'una', plurals 'unos/unas'. | a, an; one | Me pidió un vaso de agua. He asked me for a glass of water. | |
| 3 | usted Takes third-person singular verb forms: usted es, usted tiene. Abbreviated Ud. in writing. In Colombia and parts of the Andes it is also used with family and friends. | you (formal, singular) | ¿Usted también trabaja aquí? Do you work here too? (formal) | |
| 4 | ustedes In Latin America it covers both formal and informal plural; in Spain it is formal only, since the informal plural is 'vosotros' (¿Ya habéis cenado?). | you (plural) | ¿Ustedes ya cenaron? Have you all had dinner already? | |
| 5 | usar Also 'to wear' for clothes, glasses or perfume: usa gafas (Spain) / usa lentes (Mexico). | to use; to wear | No sé usar esta lavadora. I don't know how to use this washing machine. | |
| 6 | último Adjective: última, últimos, últimas. 'El último modelo' means the latest model, not the final one. | last, latest | Fui el último en llegar. I was the last one to arrive. | |
| 7 | útil Same form for masculine and feminine; plural 'útiles'. Stress on the first syllable, hence the accent. | useful, handy | Este consejo me fue muy útil. This piece of advice was very useful to me. | |
| 8 | uva Feminine. In Spain people eat twelve grapes at midnight on New Year's Eve. | grape | Compré un kilo de uvas verdes. I bought a kilo of green grapes. | |
| 9 | uña Feminine. 'Ser uña y carne' means to be inseparable. | fingernail, toenail; claw | Se muerde las uñas cuando está nerviosa. She bites her nails when she's nervous. | |
| 10 | universidad Feminine. Spanish keeps the article 'la' where English often drops it. | university | Mi hermana estudia en la universidad. My sister studies at university. | |
| 11 | uso Masculine noun. Identical in form to 'uso' = 'I use' (from usar); the article tells you which one it is. | use | Este cuchillo es de uso diario. This knife is for everyday use. | |
| 12 | unos Feminine 'unas'. Before a number it means 'roughly': unos veinte euros. | some, a few; about | Espera unos minutos, por favor. Wait a few minutes, please. | |
| 13 | único Before the noun it means 'only' (el único hijo = the only child); after it, 'unique' (una voz única). | only, sole; unique | Es el único que sabe la verdad. He's the only one who knows the truth. | |
| 14 | unir Reflexive 'unirse a' = to join a group: se unió al equipo. | to join, to connect, to unite | Vamos a unir las dos mesas. Let's put the two tables together. | |

| 17 | universo Masculine. | universe | Hay millones de galaxias en el universo. There are millions of galaxies in the universe. | |
| 18 | urgente Same form for both genders. 'Es urgente que' takes the subjunctive: es urgente que vengas. | urgent | Tengo que enviar un correo urgente. I have to send an urgent email. | |

| 20 | usuario Masculine; feminine 'usuaria'. 'Nombre de usuario' = username. | user | El usuario tiene que crear una contraseña. The user has to create a password. | |
| 21 | utilizar A step more formal than 'usar' and never means 'to wear'. Common in manuals and instructions. | to use, to utilise | Utilizamos aceite de oliva para todo. We use olive oil for everything. | |
| 22 | ubicación Feminine. This is the standard word on phones and map apps in Spain and Latin America alike. | location | Mándame tu ubicación por mensaje. Send me your location by text. | |
| 23 | ubicar In Mexico, 'ubicar a alguien' also means to recognise or place someone: no lo ubico. | to locate, to place | No consigo ubicar el restaurante en el mapa. I can't find the restaurant on the map. | |
| 24 | untar Used for butter, jam, cream or ointment. Reflexive for creams: úntate protector solar. | to spread, to smear | Unta un poco de mantequilla en el pan. Spread a bit of butter on the bread. | |

Questions about this deck
- What is the difference between usar and utilizar?
- They overlap almost completely, but 'usar' is the everyday choice in speech (usa el móvil, no sé usar esto) and it also means 'to wear': usa gafas. 'Utilizar' sounds more technical or formal and is what you see in manuals, reports and instructions. If in doubt, say 'usar'.
- When does uno become un?
- 'Uno' stands alone as the number: solo tengo uno. Right before a masculine singular noun it shortens to 'un': un coche, un año. The feminine is 'una' in both positions: tengo una, una casa. The same shortening happens in compounds: veintiún libros, treinta y un días.
- Why do I sometimes see u instead of o for "or"?
- Spanish replaces 'o' with 'u' before a word that begins with the o- sound, so two identical vowels don't collide: siete u ocho, ayer u hoy, mujeres u hombres. The next word may be spelled o- or ho-, since the h is silent. Before other sounds you keep 'o': siete o nueve.
- Is ubicación used in Spain or only in Latin America?
- Both. 'Ubicación' is what phones and map apps say everywhere ('compartir ubicación'), and Spaniards use it too. In Spain you will also hear 'localización' or simply 'sitio' in casual speech, while in Mexico and much of Latin America 'ubicación' and the verb 'ubicar' are far more frequent day to day.
