What Are Conjunctions in Spanish? (With Examples)


If your Spanish sometimes feels choppy, conjunctions are usually the missing piece.

Conjunctions are short connecting words like y (and), pero (but), and porque (because). They link ideas so your sentences sound natural instead of disconnected.

This guide explains what conjunctions in Spanish are, how to use the most common ones, and where learners usually make mistakes. If you want more advanced connectors for storytelling, check out our guide to Spanish transition words and connectors.

Real-World Focus

This guide is for Spanish learners who want to sound natural in conversation. We’ll focus on the most common conjunctions you hear every day, not academic writing rules.


What Are Conjunctions in Spanish?

Spanish conjunctions are words that connect:

  • words: pan y queso
  • phrases: en casa o en la oficina
  • clauses: No fui porque estaba cansado

In practice, conjunctions help you explain reasons, show contrast, add details, and present options.


Why Conjunctions Matter

Imagine trying to explain why you’re late to a friend using only basic vocabulary:

Without conjunctions: Perdón. Llego tarde. Había tráfico. Mi carro no funcionaba. With conjunctions: Perdón que llegue tarde, pero había mucho tráfico y además mi carro no funcionaba bien.

The second version sounds smoother because the ideas are connected.


5 Conjunctions You Will Use Most

If you learn these first, you can handle most everyday conversations.

1. Pero vs Sino

This is one of the most common learner mistakes. Here is the core rule:

The Golden Rule

Pero = “but” (adds contrast)
Sino = “but rather” (corrects/replaces something)

Use SINO only after negative statements to correct them.

Examples that work:

  • Me gusta la pizza, pero no la hawaiana. (I like pizza, but not Hawaiian.)
  • No quiero pizza, sino tacos. (I don’t want pizza, but rather tacos.)

Common mistake:

  • ❌ Me gusta la pizza, sino no la hawaiana.
  • ❌ No quiero pizza, pero tacos.

2. Y (and)

Y is everywhere, but it changes form to sound better:

Y → E when the next word starts with “i” or “hi” sound:

  • Padre e hijo (not “padre y hijo”)
  • Agua e hielo (not “agua y hielo”)

Common examples you’ll hear:

  • ÂżVamos al cine o quedamos en casa? (movies or staying home?)
  • Necesito pan, leche e ingredientes para la cena. (bread, milk and ingredients)

3. O (or)

O → U when the next word starts with “o” or “ho”:

  • Siete u ocho personas (not “siete o ocho”)
  • Mujer u hombre (not “mujer o hombre”)

4. Porque (because)

This one’s straightforward—use it exactly like “because” in English:

  • No fui porque estaba enfermo. (I didn’t go because I was sick.)
  • Me gusta porque es divertido. (I like it because it’s fun.)

5. Aunque (although/even though)

Use this when you want to say “even though” or “although”:

  • Voy a salir aunque llueva. (I’m going out even though it’s raining.)
  • Me gusta la pelĂ­cula, aunque es larga. (I like the movie, although it’s long.)

Real Conversation Examples

Here’s how these conjunctions sound in actual conversations:

Scenario 1: Making Weekend Plans

María: ¿Quieres ir al cine o prefieres quedarte en casa? Juan: Me gustaría ir al cine, pero no tengo dinero. María: No te preocupes, yo invito. Además, hay una película nueva que quiero ver. Juan: Perfecto, aunque prefiero comedias que dramas.

Scenario 2: Explaining Why You’re Late

Perdón que llegue tarde. Salí temprano de casa, pero había mucho tráfico en la avenida principal. Además, paré por gasolina y la fila estaba larguísima. Así que decidí tomar otra ruta, aunque era más larga.

Scenario 3: Polite Disagreement

Ana: Creo que deberíamos ir a la playa este fin de semana. Luis: Me gusta la idea; sin embargo, el pronóstico dice que va a llover. Ana: Es cierto, pero podríamos ir aunque llueva un poco. Luis: No sé… prefiero no ir a la playa, sino al museo. O sea, podemos hacer algo interior.


Common Mistakes (And How to Fix Them)

Mistake #1: Confusing “Pero” and “Sino”

The Problem: Most English speakers use “pero” for everything because it seems like “but.”

Wrong: No quiero café, pero té.
Right: No quiero café, sino té.

Quick Fix: If you can replace it with “but rather” in English, use “sino” in Spanish.

Mistake #2: Forgetting Sound Changes

The Problem: Saying “y” when it sounds awkward.

Wrong: Madre y hijo (sounds clunky)
Right: Madre e hijo (flows naturally)

Quick Fix: If saying “y” + the next word creates an awkward “ee” sound, change it to “e.”

Mistake #3: Overusing Formal Conjunctions

The Problem: Using fancy words in casual conversation.

Sounds Weird: Quiero pizza; no obstante, también me gusta la pasta.
Sounds Natural: Quiero pizza, pero también me gusta la pasta.

Quick Fix: Save the fancy words (sin embargo, no obstante) for when you want to sound polite or formal.

Regional Notes

Latin America vs Spain

“Así que” vs “Entonces”

  • Latin America: Estaba lloviendo, asĂ­ que me quedĂ© en casa.
  • Spain: Estaba lloviendo, entonces me quedĂ© en casa.

Both are correct, but knowing the difference helps you sound more natural in different regions.

Casual Fillers That Act Like Conjunctions

“O sea” - Super common in Latin America:

  • No me gustĂł la pelĂ­cula, o sea, fue aburrida.
  • LleguĂ© tarde, o sea, habĂ­a tráfico.

“Pues” - More common in some regions:

  • No fui, pues estaba enfermo.

Sound More Natural

Don’t be afraid to use “o sea” in casual conversation—it’s like saying “I mean” or “like” in English. Native speakers use it constantly to soften statements or rephrase things.


A Simple 4-Week Practice Plan

Week 1: Focus on pero vs sino. Every time you say “but,” ask: contrast or correction?

Week 2: Practice sound changes: y -> e and o -> u.

Week 3: Add porque, aunque, and asĂ­ que in daily speaking.

Week 4: Add sin embargo, además, and o sea.

Daily practice: Pick one conjunction and use it in 3 short sentences.


Quick Reference

These are the conjunctions you will use most often:

Essential Conjunctions

Basic Connections:

  • y (and) → e before “i/hi” sounds
  • o (or) → u before “o/ho” sounds
  • pero (but) - for contrast
  • sino (but rather) - for correction after negative
  • porque (because)
  • aunque (although/even though)

Level Up:

  • asĂ­ que (so/therefore)
  • por eso (that’s why)
  • además (besides/also)
  • sin embargo (however - polite)
  • en cambio (on the other hand)
  • o sea (I mean - casual)

When to Use Each One

Quick Decision Tree

Contrasting? → Use pero
Correcting after “no”? → Use sino
Giving a reason? → Use porque
Being polite but disagreeing? → Use sin embargo
Adding information? → Use además or y
Explaining a result? → Use así que or por eso


The Bottom Line

You do not need to memorize dozens of conjunctions to sound natural in Spanish. You need to use the most common ones correctly and consistently.

Start with pero vs sino. Then add the sound changes (y -> e, o -> u). Those two steps alone improve your Spanish quickly.

Then build from there with porque, aunque, and asĂ­ que.

Common Questions About Spanish Conjunctions

When do I use 'pero' vs 'sino'? +
Use pero for any contrast (like 'but' in English). Use sino only after negative statements to correct or replace something. Think 'but rather' - if that works in English, use 'sino' in Spanish.
Why do 'y' and 'o' sometimes change to 'e' and 'u'? +
It's all about sound flow. Spanish speakers naturally avoid awkward vowel combinations. Y becomes e before 'i' sounds, and o becomes u before 'o' sounds. Just listen to how it sounds - the change always sounds more natural.
Should I use formal conjunctions like 'sin embargo' in casual conversation? +
It depends on the situation. Sin embargo is perfect for polite disagreement or when you want to sound respectful. For casual chat with friends, pero usually works fine. Think of it like 'however' vs 'but' in English.
What's the difference between 'asĂ­ que' and 'por eso'? +
Both mean 'so/therefore' but they feel slightly different. AsĂ­ que connects cause and effect smoothly ('I was tired, so I left'). Por eso emphasizes the reason more ('That's why I left'). Both are natural - use whichever feels right.

Ready to Sound Like a Native?

Mastering Spanish conjunctions is mostly about repetition in real conversations. Start with the core set, use them daily, and add new ones gradually.

Remember: pero vs sino is the most important distinction to lock in early.
