Language & WorldFact
Your letter A used to be an ox head.
Around 1050 BC, Phoenician traders used an alphabet of 22 consonant signs. The first letter, 'aleph', meant ox and showed a head with horns; rotate it and you get our A. Greeks added vowels, Etruscans and Romans adopted it. Hebrew and Arabic descend from the same alphabet.
