Ꜭ

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, , was used for the alveolar ejective affricate found in the same languages.
