The Mysterious Ü in Spanish: What It Means and How to Use It

By Lingobi, Published on 10/14/2025

If you’ve ever seen the letter Ü in Spanish words like pingüino or vergüenza, you might have wondered — what’s up with the two dots? Don’t worry, it’s not as complicated as it looks. This little symbol is called a diéresis (or diaeresis in English), and it plays a small but important role in Spanish pronunciation.

When Do You Use the Ü?

Normally, when you see the letter “u” between g and e or i in Spanish — like in guerra (war) or guitarra (guitar) — the “u” is silent. But if you add the two dots, the “u” becomes pronounced.

Without the dots: guerra → sounds like “GEH-rra” (silent u)

With the dots: pingüino → sounds like “peen-GWEE-no” (the u is pronounced)
