Connecting Ideas in Spanish: Your Ultimate Guide to Basic Conjunctions

Ever tried telling a story without using "and" or "but"? It would sound a bit like a robot, right? "I went to the store. I bought milk. The milk was expensive." It's clunky and disconnected.

The little words that stitch our sentences together are called conjunctions. Think of them as the glue of language. They turn choppy phrases into smooth, flowing ideas. In Spanish, mastering a few basic conjunctions will instantly make your speech sound more natural and sophisticated.

A friendly, smiling bottle of glue labeled "Conjunción" is connecting two separate floating puzzle pieces, one with a drawing of the sun and the other with a drawing of a moon. Charming ink and watercolor painting, clean lines, vibrant but soft color palette, storybook style, dark background.

In this guide, we'll unpack the most essential Spanish conjunctions. Get ready to connect your ideas like a pro!

The "And" Conjunctions: Y vs. E

The most common way to say "and" in Spanish is y. Simple, right?

  • Perros yand gatos (Dogs and cats)
  • Me gusta leer yand escribir (I like to read and write)
  • Tacos yand burritos (Tacos and burritos)

But wait, there's a little twist!

The Golden Rule of "E"

Spanish values flow and rhythm. Saying y before a word that starts with a similar "ee" sound (written as i- or hi-) is a bit of a tongue-twister. To solve this, Spanish swaps y for e.

A visual metaphor of sound waves. On the left, a blue sound wave labeled 'y' awkwardly bumps into a yellow sound wave labeled 'i', creating little cartoon sparks. On the right, a blue sound wave labeled 'e' flows and merges seamlessly with a yellow sound wave labeled 'i'. Charming ink and watercolor painting, clean lines, vibrant but soft color palette, storybook style, dark background.

Rule: Use e instead of y when the following word starts with an i- or hi- sound.

Necesito aguja y hilo.

Necesito aguja e hilo.

Sound Check!

This rule is all about pronunciation. The word hielo (ice) starts with a silent "h," so its sound begins with "ie-". That's why we say agua e hielo, not agua y hielo.

The "Or" Conjunctions: O vs. U

Just like with "and," there's a primary word for "or" and a special exception. The standard word is o.

  • ¿Quieres té oor café? (Do you want tea or coffee?)
  • Podemos ir hoy oor mañana. (We can go today or tomorrow.)

The "U" Exception

Can you guess the rule here? It's the exact same logic as the y/e rule, but for the "oh" sound! To avoid the awkwardness of saying o before a word that starts with an o- or ho- sound, Spanish swaps o for u.

Rule: Use u instead of o when the following word starts with an o- or ho- sound.

Incorrecto ❌Correcto ✅

Siete o ocho minutos.

Siete u ocho minutos.

La víctima era mujer o hombre.

La víctima era mujer u hombre.

The "But" Conjunctions: Pero vs. Sino

This is where many learners get tripped up, but the difference is simpler than you think. Both pero and sino can be translated as "but," but they are used in different situations.

A split-panel illustration. On the left, a path has a small boulder on it, with a sign that says "PERO." A cartoon character easily walks around it. On the right, a path leads to a large red 'X' sign. A helpful signpost labeled "SINO" points to a completely different, clear path.

Pero: The Classic "But"

Pero is your go-to conjunction for "but" or "however." It adds contrasting information or an objection to the first part of the sentence, but it doesn't cancel it out. For a deeper understanding of sentence structure, check out our guide on whether to use ser or estar.

  • El coche es rápido, perobut gasta mucha gasolina. (The car is fast, but it uses a lot of gas.)
  • Quiero ir a la fiesta, perobut tengo que trabajar. (I want to go to the party, but I have to work.)

In both examples, the first part of the sentence is still true. The car is fast. I do want to go to the party. Pero just adds a complication.

Sino: The "But Rather"

Sino is a bit different. It's used to correct or contradict a negative statement. Think of it as meaning "but rather" or "instead."

Rule: Use sino only when the first part of the sentence is negative (e.g., uses no), and the second part provides the correct information.

  • No quiero té, sinobut rather café. (I don't want tea, but rather coffee.)
  • El suéter no es azul, sinobut rather verde. (The sweater isn't blue, but rather green.)

Here, sino completely negates the first idea. I don't want tea at all. The sweater is not blue in any way.

Pero vs. Sino: The Key Difference

Ask yourself: Is the first statement negative (no, nunca, etc.) and am I directly correcting it?

  • If YES, use sino.
  • If NO, use pero.

La película es larga, ___ interesante.


No fuimos a la playa, ___ a la montaña.

Frequently Asked Questions

What is the difference between 'y' and 'e' in Spanish?

Both mean 'and', but you use 'e' instead of 'y' when the word that follows starts with an 'i-' or 'hi-' sound. For example, 'padre e hijo' (father and son).

When do I use 'pero' vs. 'sino'?

Use 'pero' (but) to add contrasting information. Use 'sino' (but rather/instead) only after a negative statement to introduce a direct correction or alternative. For example, 'Es caro, pero me gusta' (It's expensive, but I like it) vs. 'No es rojo, sino azul' (It's not red, but rather blue).

Is there a rule like 'y/e' for the word 'o' (or)?

Yes! 'O' changes to 'u' when the word that follows starts with an 'o-' or 'ho-' sound. For example, 'siete u ocho' (seven or eight).
