Tresillo
Tresillo is a letter of several colonial Mayan alphabets in the Latin script that is based on the digit 3. It was invented by a Franciscan friar, Francisco de la Parra, in the 16th century to represent the uvular ejective consonant found in Mayan languages, and is known as one of the Parra letters. In cursive form, the tresillo is often written.
