Aleph

Aleph (or alef or alif, transliterated ʾ) is the first letter of the Semitic abjads, including Phoenician 𐤀, Hebrew א, Aramaic 𐡀, Syriac ܐ, Arabic ʾ ا, and North Arabian 𐪑. It also appears as South Arabian 𐩱 and Ge'ez አ. These letters are believed to have derived from an Egyptian hieroglyph depicting an ox's head to describe the initial sound of *ʾalp, the West Semitic word for ox (compare Biblical Hebrew ʾelef, "ox"). The Phoenician variant gave rise to the Greek alpha (Α), being re-interpreted to express not the glottal consonant but the accompanying vowel, and hence the Latin A and Cyrillic А.
