How to Say 'Either' in Spanish | Exact Meanings And Usage

Ad-network review: Pass

In Spanish, “either” is usually “o”, “cualquiera”, “uno u otro”, or “tampoco”, depending on the sense you mean.

In English, “either” can point to a choice, a person, a thing, or a reply. Spanish can do all of that too, but it spreads the work across different words and sentence shapes. Once you spot what “either” is doing, the Spanish becomes straightforward.

You’ll get clear translations, short explanations, and sentence patterns you can reuse in classwork, messages, and formal writing. All sample lines are original, built to show how Spanish is normally said.

How To Say ‘Either’ In Spanish In Real Sentences

Start by sorting “either” into one of three meanings. This tiny step saves a lot of rewrites.

Choice: “Either A or B.” You’re linking options.
One of two: “Either one is fine.” You’re pointing to any one item from a set of two.
Negative agreement: “Me either.” You’re agreeing with a negative sentence.

If your English sentence could be rewritten without the word “either” and keep the same meaning, Spanish often drops it too. That’s normal. Spanish aims for clean wording, not a word-for-word mirror.

Saying “Either” For A Choice Between Options

When “either” introduces a choice, Spanish most often uses o (“or”). In many sentences, you don’t need a direct Spanish twin of “either” at all.

Using “O” With Short Choices

English: Either tea or coffee.
Spanish: Té o café.

English: You can send it either today or tomorrow.
Spanish: Puedes enviarlo hoy o mañana.

When You Want A Clear “Either…Or…” Frame

English sometimes uses “either…or…” to signal a clean two-part frame. Spanish has a couple of patterns that keep that rhythm, mainly in writing and speeches.

Pattern 1: Ya Sea + Option A + O + Option B

English: Either by bus or by train, we’ll arrive before noon.
Spanish:Ya sea en autobús o en tren, llegaremos antes del mediodía.

Pattern 2: Sea + Option A + O + Option B

English: Either you call me, or I’ll call you.
Spanish:Sea me llamas o te llamo yo.

In casual talk, most speakers stick with plain o and move on. The longer patterns shine when you want a balanced, formal cadence.

When “O” Changes To “U”

Spanish changes o to u before words that start with an “o” sound. It avoids the double “o” sound back to back.

English: seven or eight
Spanish: siete u ocho

English: one thing or another
Spanish: una cosa u otra

This spelling change is standard in Spanish writing. You can confirm it in Real Academia Española notes on the conjunction o.

What To Say For “Either Way”

English “either way” means “no matter which option happens.” Spanish has a few natural picks, with small shifts in tone.

De cualquier manera (neutral)
De todos modos (casual)
Igual (short and informal in many regions)

English: Either way, I’m going.
Spanish:De cualquier manera, voy.

Using “Either” To Mean “One Of Two”

Now the meaning shifts. You’re not linking A and B. You’re pointing to a set of two and saying that either member of the set works. Spanish often uses cualquiera or uno u otro.

Cualquiera, Cualquier, And “De Los Dos”

Cualquiera means “any one.” If you want to stress that it’s a set of two, add de los dos (masculine) or de las dos (feminine).

English: Either book works for the class.
Spanish:Cualquiera de los dos libros sirve para la clase.

English: You can sit in either seat.
Spanish: Puedes sentarte en cualquiera de los dos asientos.

Before a singular noun, Spanish often uses the short form cualquier:

Cualquier día sirve.
Cualquier opción vale.

When you need to keep the “two” idea visible, the de los dos add-on keeps your meaning tight.

Uno U Otro, Una U Otra

Uno u otro matches “either one” in a direct, clean way. It’s handy when both options are already known in the chat or text.

English: Either one is fine.
Spanish:Uno u otro está bien.

English: Choose either answer.
Spanish: Elige una u otra respuesta.

Watch gender. Use uno with masculine nouns and una with feminine nouns.

Either Of Us, Either Of Them, Either Parent

English likes “either of + pronoun.” Spanish usually flips the order and places the “either” idea after the verb.

English: Either of us can explain it.
Spanish: Podemos explicarlo cualquiera de los dos.

English: Either of them can sign.
Spanish: Puede firmar cualquiera de los dos.

English: Either parent can attend the meeting.
Spanish: Puede asistir a la reunión cualquiera de los dos padres.

That verb-first order reads naturally in Spanish and keeps attention on the action.

Here’s a quick map from common English uses to natural Spanish picks:

Meaning In English	Spanish Options	When It Fits
Either A or B (simple choice)	o	Lists and quick choices
Either…or… (balanced writing)	ya sea… o…, sea… o…	Formal cadence, two-part frame
Or before an “o” sound	u	Spelling rule: “u ocho”
Either way	de cualquier manera, de todos modos, igual	“No matter which option”
Either one (any of two)	cualquiera, uno/una u otro/otra	Both options work
Either of the two (explicit set)	cualquiera de los dos / de las dos	Stresses a set of two
Either of us / them	Verb + cualquiera de los dos	Common Spanish word order
Me either / me neither	yo tampoco, a mí tampoco	Reply to a negative sentence
I don’t… either (full sentence)	tampoco + verb / subject + tampoco	Works in replies and statements
Neither… nor…	ni… ni…	Two negatives in one line

Agreeing With A Negative: “Me Either” In Spanish

After a negative sentence, English can reply with “me either” or “me neither.” Spanish usually replies with tampoco. You can say it alone, or add a pronoun for clarity.

English: I don’t like onions.
Spanish: No me gustan las cebollas.
Reply:Yo tampoco.

English: I can’t go today.
Spanish: No puedo ir hoy.
Reply:A mí tampoco.

Spanish keeps the negative in the first sentence. The reply does not say no again. Tampoco carries the agreement.

Using “Tampoco” Inside A Full Sentence

English often adds “either” at the end: “I don’t like it either.” Spanish can place tampoco near the start, or after the verb. Both are common.

English: I don’t like it either.
Spanish:Tampoco me gusta.

English: I don’t want dessert either.
Spanish:Tampoco quiero postre.

English: She doesn’t study either.
Spanish: Ella tampoco estudia.

Neither…Nor… Uses “Ni…Ni…”

When English uses “neither…nor…”, Spanish uses ni… ni…. It pairs well with the normal Spanish negative pattern.

English: I like neither tea nor coffee.
Spanish: No me gusta ni el té ni el café.

English: He called neither yesterday nor today.
Spanish: No llamó ni ayer ni hoy.

Notice the double negative style. That’s standard Spanish grammar, not “bad Spanish.”

Quick Fixes For Common Mix-Ups

These mistakes show up in homework and messages all the time. The fixes are simple once you know what Spanish expects.

Mix-Up 1: Using “También” After A Negative

Wrong idea: “I don’t like it.” → “Me too.”

In English, “me too” can show agreement in many situations. In Spanish, after a negative, use tampoco, not también.

English: I don’t like it.
Spanish: No me gusta.
Reply:Yo tampoco.

Mix-Up 2: Adding “No” In The Reply

Learners sometimes write “yo no tampoco.” Spanish does not use that structure. Use yo tampoco or a mí tampoco.

Mix-Up 3: Using Cualquiera When You Mean A Choice

Cualquiera means “any one.” If you’re linking two options, you want o.

English: Either Monday or Tuesday.
Spanish: Lunes o martes.

English: Either day works.
Spanish: Sirve cualquiera de los dos días.

Mix-Up 4: Forgetting Gender In “Uno U Otro”

Match the noun:

uno u otro libro
una u otra respuesta

Mix-Up 5: Copying English Word Order

English says “either of them can…” and starts with “either.” Spanish often places the “either” idea after the verb:

Spanish pattern: Puede + verb phrase + cualquiera de los dos.

English Pattern	Natural Spanish Pattern	Note
Either A or B	A o B	“Either” often drops
Either this or that	Esto o aquello / una cosa u otra	Use u before “o” sound
Either…or… (formal rhythm)	Ya sea A o B	Common in writing
Either one is fine	Uno u otro está bien	Match gender when needed
Either of the two	Cualquiera de los dos	Often placed after verb
Me either	Yo tampoco / A mí tampoco	Reply to a negative
I don’t like it either	Tampoco me gusta	Short and natural
Neither… nor…	No + verb + ni… ni…	Standard double negative

Five Minute Practice Plan

If you want this to stick, practice meaning first, not translation first. Here’s a short routine that works well for learners.

Name the job. Choice, one-of-two, or negative agreement?
Pick the pattern.o; cualquiera/uno u otro; or tampoco.
Say it once out loud. Your ear catches clunky word order faster than your eyes do.
Write one extra sentence. Change only the subject or the noun. Keep the pattern.

Try these prompts. Write your Spanish line under each one.

Either Monday or Tuesday works.
Either answer is acceptable.
I can’t stay late. — Me either.
I don’t want dessert either.
