Tresillo

Tresillo (capital: Ꜫ, small: ꜫ; Spanish for "little three") is a letter of the Latin alphabet, based on the digit 3. It was invented by a Franciscan friar, Alonso de la Parra, in the 16th century to represent the uvular ejective consonant /qʼ/ found in Mayan languages, and is known as one of the Parra letters. In cursive form, the tresillo is often written c ̑.
