"When the Greeks adapted the Phoenician alphabet to write their language they used five of the Phoenician consonants to represent vowel sounds: yodh (𐤉) [j] became Ι (iota), waw (𐤅) [w] became Υ (upsilon), 'aleph (𐤀) [ʔ] became Α (alpha), 'ayin (𐤏) [ʕ] became Ο (omicron), and he (𐤄) [h] became Ε (epsilon). New letters were also devised: Φ (phi), Χ (chi) and Ψ (psi). The result was the world's first fully phonemic alphabet which represented by consonant and vowel sounds."
