How to Say I'm Thirsty in Spanish

You're hiking above Cusco, the sun is merciless, and you gasp "Soy sediento" to your guide. He hands you a water bottle anyway, but he's smiling, because you just said you are a thirsty person by nature. Knowing how to say I'm thirsty in Spanish takes one small verb switch, and it will keep you hydrated on every trip.

Why "I'm Thirsty" Isn't "Soy Sediento"

In English, thirst is something you are: "I'm thirsty," "I'm hungry," "I'm cold." Spanish treats it as something you have. Just as you have a birthday or have an age, you have thirst, as a sensation that visits you.

That's why the everyday phrase for I'm thirsty in Spanish uses tener (to have), not ser or estar. The pattern covers a whole family of physical sensations, so learning it once pays off many times over.

If you've already met tengo frío or tengo hambre, this post will feel familiar, and it adds a few thirst-specific tricks you won't find elsewhere.

The Core Phrase: Tengo Sed

The phrase you need is tengo sed (I have thirst), which means I'm thirsty. Notice there is no article: not tengo la sed or tengo una sed. Just tener plus the noun.

Key Phrases

• Tengo sed (TEHN-goh SEHD) — I'm thirsty
• Tienes sed (tee-EH-nehs SEHD) — you're thirsty (informal)
• Tiene sed (tee-EH-neh SEHD) — he/she is thirsty, or you are (formal)
• Tenemos sed (teh-NEH-mohs SEHD) — we're thirsty
• ¿Tienes sed? (tee-EH-nehs SEHD) — are you thirsty?
• Tengo mucha sed (TEHN-goh MOO-chah SEHD) — I'm very thirsty

Grammar Note

Tener is irregular, so memorize its present tense as a unit. The pattern below shows how it pairs with sed:

• yo tengo sed
• tú tienes sed
• él/ella/usted tiene sed
• nosotros tenemos sed
• ellos/ellas/ustedes tienen sed

Because sed is a noun, you intensify it with an adjective, not an adverb. Say mucha sed (a lot of thirst), never muy sed. The adjective matches the feminine noun, so it is always mucha, poca, tanta.

• Common mistake: Soy sediento says you are a thirsty person by nature, so use tengo sed.
• Common mistake: Tengo muy sed uses an adverb where Spanish wants mucha.

Sediento, Seco, and Other Ways to Say It

Tengo sed is the default, but you'll hear other options. Estar sediento (to be thirsty) exists and is correct, yet it sounds poetic, like "parched" in English. You'll meet it in novels and news stories, rarely at the dinner table.

More colorful versions are everywhere in casual speech:

• Me muero de sed (meh MWEH-roh deh SEHD) — I'm dying of thirst
• Estoy seco/seca (ehs-TOY SEH-koh/SEH-kah) — I'm parched (literally, dry)
• Tengo la garganta seca (TEHN-goh lah gahr-GAHN-tah SEH-kah) — my throat is dry
• Me da sed (meh dah SEHD) — it makes me thirsty
• Estoy sediento/sedienta (ehs-TOY seh-dee-EHN-toh/tah) — I'm thirsty (formal, literary)

Use me muero de sed for drama, as in "I'm dying of thirst after that run." Use me da sed for causes, as in Esta comida salada me da sed (this salty food makes me thirsty).

In much of Latin America, offering a drink is the first act of hospitality. In Mexico, a host may say "¿Qué te sirvo?" (what can I pour you?) before you've even sat down. Refusing outright can feel cold, so "Un poco de agua, por favor" is a gracious reply. In Colombia and Venezuela, a cold jugo natural (fresh juice) is the standard way to cure thirst on a hot day.

Asking for Something to Drink

Saying you're thirsty is rarely the end of the conversation. Usually you want a drink. These are the phrases that turn thirst into water, politely.

Key Phrases

• Quisiera un vaso de agua (kee-see-EH-rah oon BAH-soh deh AH-gwah) — I'd like a glass of water
• ¿Me puede traer agua, por favor? (meh PWEH-deh trah-EHR AH-gwah) — could you bring me water, please?
• ¿Hay algo de beber? (eye AHL-goh deh beh-BEHR) — is there something to drink?
• Agua con gas / sin gas (AH-gwah kohn gahs / seen gahs) — sparkling / still water
• Agua del grifo (AH-gwah dehl GREE-foh) — tap water (Spain; in Latin America, often agua de la llave)

Be careful with tomar and beber. Both mean to drink, but tomar is far more common in Latin America, while beber sounds a touch more formal. Either will be understood everywhere.

In Mexico a waiter may ask ¿Agua natural o mineral?, where natural means still, not "from nature."

Putting It to Work

Here is a short exchange you can borrow the next time you're at a friend's house or a café:

• Anfitrión: ¿Tienes sed?
• Tú: Sí, tengo muchísima sed. ¿Hay agua?
• Anfitrión: Claro, ¿con gas o sin gas?
• Tú: Sin gas, por favor. ¡Gracias!

For kids, family, or friends, the informal tienes sed is perfect. With strangers, elders, or in a restaurant, switch to tiene sed or the polite ¿Le gustaría algo de beber? (would you like something to drink?).
