Cuatrillo

Cuatrillo (capital: Ꜭ, small: ꜭ) (Spanish for "little four") is a letter of several colonial Mayan alphabets in the Latin script that is based on the digit 4. It was invented by a Franciscan friar, Alonso de la Parra, in the 16th century to represent the velar ejective consonant found in Mayan languages, and is known as one of the Parra letters.

A derivative of the cuatrillo by adding a diacritic, $⟨Ꜯ ꜯ⟩$, was used for the alveolar ejective affricate found in the same languages.

The cuatrillo is encoded in Unicode at the code points and, respectively. The cuatrillo-commas are at and.

As an example of use, the letter appears when spelling the name of the Kʼicheʼ language in the Parra orthography: ꜭiche.
