A deep dive into Spain’s 3 co-official languages: Catalan, Galician & Basque

When people think of Spain, they naturally think of the Spanish language. But did you know that Castilian Spanish isn’t the only official language spoken in the country? Spain is home to a rich linguistic tapestry, with several languages holding official status in their respective regions.
This guide will take you on a deep dive into the three largest co-official languages that define the cultural identity of their communities: Catalan, Galician, and Basque.
Forget what you might have heard about them being simple dialects—these are complete, vibrant languages with their own history, culture, and soul.
What does “co-official” really mean?
Before we explore each language, it’s important to understand what “co-official” means. The Spanish Constitution of 1978 officially recognized the country’s multilingual reality after decades of suppression.
While Castilian Spanish remains the sole official language nationwide, the constitution grants “co-official” status to other languages in their corresponding autonomous communities.
This means they have equal legal standing in government, public administration, education, and media within those regions.
You’ll see them on street signs, hear them on TV, and study them in schools. This framework allows each language to thrive as a living, breathing part of modern Spanish society.
Basque (Euskera): Europe’s ancient mystery
Where is it spoken? Basque is spoken in the Basque Country and the northern part of Navarre, two autonomous communities located in the western Pyrenees, bordering France.

A Language Isolate Basque is the linguistic jewel of Spain—and a complete mystery. It is a language isolate, meaning it is unrelated to any other known language family in the world.
It predates the arrival of Latin and other Indo-European languages in Europe, making it the oldest living language on the continent. Its origins have puzzled linguists for centuries, with its survival being nothing short of remarkable.
Linguistic curiosities
Basque grammar and vocabulary are entirely different from Spanish, English, or French. For example, it uses a vigesimal (base-20) system for counting, and its verb structure is incredibly complex, changing based on who is being spoken to.
Its complete otherness makes it a challenge to learn but a fascinating subject for anyone interested in linguistics.
Practical phrases for travelers

| Hello | Kaixo | kai-sho |
| Thank you | Eskerrik asko | es-keh-rreek ahs-ko |
| Please | Mesedez | meh-seh-dess |
| Goodbye | Agur | ah-goor |
Galician (Galego): The atlantic language of poets
Where is it spoken? Galician is the co-official language of Galicia, the lush, green region in Spain’s northwestern corner, just above Portugal.

A shared past with Portuguese
Galician’s history is deeply intertwined with its southern neighbor. Both languages evolved from a common medieval ancestor: Galician-Portuguese.
For centuries, this was the language of lyric poetry across the Iberian Peninsula. While the languages eventually diverged, they remain highly mutually intelligible.
Galicia’s most celebrated writer, Rosalía de Castro, became a key figure in the 19th-century revival of Galician as a literary language.
Linguistic curiosities
Galician is known for its soft, musical intonation. It contains unique words that reflect the region’s culture, the most famous of which is “morriña”—a profound, bittersweet feeling of longing and nostalgia for one’s homeland. It’s a word that captures the essence of the Galician diaspora experience.

| Hello | Ola | oh-lah |
| Thank you | Grazas | grah-thass |

Catalan (Català): The mediterranean voice
Where is it spoken? Catalan is spoken in Catalonia, the Balearic Islands, and the Valencian Community (where it’s known as Valencian). It’s also spoken in a small strip of Aragon and in the neighboring country of Andorra.

A glimpse into its history
Catalan has a proud history, flourishing as a major literary and administrative language during the Middle Ages. After centuries of prestige, it faced a steep decline and was heavily repressed during the Franco dictatorship in the 20th century.
However, since the return of democracy, Catalan has experienced a remarkable resurgence and is now a dynamic and integral part of the region’s identity, especially in its capital, Barcelona.
Linguistic curiosities
As a Romance language, Catalan shares similarities with Spanish, French, and Italian. However, it has distinct features that set it apart.
For instance, it uses the unique letter combination l·l (called a ela geminada), which produces a sound similar to “l” followed by another “l” (as in “il·legal”).
While a Spanish speaker can often understand written Catalan, the pronunciation and rhythm are markedly different.
Practical phrases for travelers
| English | Catalan | Simple pronunciation |
|---|---|---|
| Hello | Bon dia | bohn dee-ah |
| Thank you | Gràcies/Merci | grah-see-ess / mer-see |
| Please | Si us plau | see oos plow |
| Goodbye | Adéu | ah-deh-oo |
The languages of Spain are far more diverse than many realize. Catalan, Galician, and Basque are not footnotes in a Spanish grammar book; they are the heartbeats of their respective cultures.
Recognizing them as distinct, official languages is the first step to truly appreciating the rich and plural identity that defines modern Spain.
