What do you call the punctuation mark used in spanish spelling?

The punctuation mark used in Spanish spelling is called a tilde (pronounced "teel-day"). It is placed above the letters "a", "e", "i", "o", and "u" to indicate a change in pronunciation.

For example:

* á is pronounced like the "a" in "father"

* é is pronounced like the "e" in "bed"

* í is pronounced like the "ee" in "see"

* ó is pronounced like the "o" in "go"

* ú is pronounced like the "oo" in "moon"
