The z and c sounds in Spain (theta, ceceo and seseo)

Key rules

• Regular variants: Theta, seseo and ceceo are normal regional ways of speaking, so what you hear is not a mishearing.
• What to copy: Choose distinción or seseo, and use your choice consistently.
• Ceceo: Learn to understand ceceo, but do not use it as your model.
• Casa and caza: Distinción keeps casa and caza apart; seseo makes them sound the same.

The short answer

Pick one standard and stick to it. Distinción or seseo are both safe choices. What you hear in Spain is not you mishearing: theta, seseo and ceceo are regular regional variants, and each one is a normal way of speaking somewhere.

The three variants

Distinción keeps two sounds apart. The letter z, and c before e or i, is a "th" sound, as in English "think". The letter s is a normal "s". This is the norm in northern and central Spain and in standard, prestige speech. Because of this, "casa" (house) and "caza" (hunt) sound different.

Seseo says z and c as "s". "Casa" and "caza" then sound the same. You will hear it in the Canary Islands, in western Andalusia (parts of Huelva, Seville, Cádiz and Córdoba) and across Latin America. It carries no social stigma.

Ceceo goes the other way: it says s as the "th" sound. "Casa" then sounds like "caza". It is found in parts of southern Andalusia, such as areas of Cádiz, Málaga, Granada and Almería. It carries some social stigma.

Which one to copy

Copy distinción or seseo. Both are accepted and understood everywhere in Spain.

• Choose distinción if you want help with spelling and want to tell pairs like casa and caza apart by ear and in your own speech. It is also the standard heard in most of Spain.
• Choose seseo if you will live in the Canaries or western Andalusia, or if you learn from Latin American speakers. You lose the casa/caza difference, but context makes the meaning clear.

Whichever you pick, use it consistently. Mixing the two in one sentence is what sounds odd.

Do not copy ceceo, but learn to understand it. If you live in southern Andalusia, you will hear it daily, and it helps to know that "th" may stand for an s.

The questions below cover common worries, such as whether people will understand you and where you are most likely to hear ceceo.

Frequently asked questions

Will people understand me if I use seseo in Spain?

Yes, people across Spain understand seseo, and it is accepted as a normal way to speak. It is the everyday norm in the Canary Islands, western Andalusia and Latin America. If you choose it, use it consistently.

Which pronunciation should I copy if I want to avoid confusing casa and caza?

Copy distinción, the th sound for z and for c before e or i, if you want casa and caza to sound different. It also helps with spelling. Seseo is a fine choice too, but ceceo is not a good model to copy, though you should learn to understand it.

Where in Spain will I most likely hear ceceo?

You will most likely hear ceceo in parts of southern Andalusia, such as areas of Cádiz, Málaga, Granada and Almería. There, s is said with the th sound, so casa sounds like caza. It carries some social stigma, unlike seseo.
