“Why does everybody in Madrid have a lisp?” I’ve heard that question from students in Perth and online. The answer is a bit of history and a bit of phonetics, and it ends with good news: you can choose.
The myth of the lisping king
The legend says a Spanish king had a lisp and the court copied him out of respect. Nice story, but there’s no evidence for it. If it were true, Spaniards would also lisp the s, and they don’t.
What really happened
Medieval Spanish had several “s-like” sounds. Over the 16th and 17th centuries they simplified differently in different places:
- In the centre and north of Spain, the sound written z / ce / ci became th [θ], separate from s.
- In Seville and much of Andalusia, they merged into s. Sailors and settlers from there took that s to the Canary Islands and the Americas. That’s why Latin America says “grasias”.
Distinción, seseo and ceceo
| Name | Where | Casa (house) | Caza (hunting) |
|---|---|---|---|
| Distinción | Most of Spain | casa | catha |
| Seseo | Latin America, Canary Islands, parts of Andalusia | casa | casa |
| Ceceo | Some areas of Andalusia | catha | catha |
So the “ceceo” many foreigners talk about is actually the distinción. Ceceo is a specific Andalusian feature, and it’s the only one close to a lisp.
Words to practise the Spanish TH
| Word | Sounds like |
|---|---|
| gracias | GRA-thias |
| cerveza | ther-BE-tha |
| Barcelona | bar-the-LO-na |
| zumo | THU-mo |
| cinco | THIN-ko |
Should you use the TH?
Both are correct. If you live in Spain or love Spain, use it: it sounds natural and people notice. If you learned Latin American Spanish, keep your s: everybody in Spain understands it perfectly. What sounds strange is mixing both in the same sentence.

Why do Spaniards pronounce c and z like th?
Because of a sound change in the 16th–17th centuries in central and northern Spain. It’s called distinción and it’s standard, not a lisp.
Is it true a Spanish king had a lisp?
No. It’s a popular myth with no historical evidence.
Do all Spaniards say the th sound?
No. Most of Spain does, but the Canary Islands and parts of Andalusia use seseo (s for everything), and some Andalusian areas use ceceo.
What is the difference between seseo and ceceo?
Seseo pronounces z/ce/ci as s. Ceceo pronounces s as th. Distinción keeps both sounds separate.
Should I learn the Spanish th sound?
It’s optional. Use it if you live in or focus on Spain; otherwise the s is perfectly understood everywhere.
