Derived from Egyptian hieroglyphs via the sketchy Proto-Sinaitic script, this was the first fully phonetic alphabet. Twenty-two letters, all consonants, leaving it to the reader to infer the vowels. They can take their shapes and names from the Egyptian, but they represent only the sounds. 𐤀 The Egyptian hieroglyph for “ox head” 𓃾 𐤟 named kꜣ (or “ka”) became 𐤀 named ’ālep to represent the glottal stop.

The Greek alphabet was the first to use letters for vowel sounds. Greek didn’t use a glottal stop, so the Phoenician ’ālep became a vowel, Alpha, pronounced like the a in “father.” Greek didn’t use an H sound, so the Phoenician h’ē became the second vowel, Ε, pronounced like the e in “pet.” The Greek added the Η (eta) the third vowel, pronounced like the i in “machine.” Greek didn’t use a Y sound, so the Phoenician jōd became the fourth, Ι (iota), also pronounced like the i in “machine.” The Greek added a fifth vowel, Υ (upsilon), which, like Η and Ι is pronounced like the i in “machine.” Greek didn’t use a voiced pharyngeal fricative. so the Phoenician ‘ajin became the sixth, Ο (omicron), which means “little O,” and is pronounced like the o in German “Gott.” Greek added a seventh vowel, Ω (omega), which means “great O,” pronounced like the aw in “saw.”
Today, even Greek text is written with both majuscule and minuscule letters (both upper-case and lower-case). The minuscules were developed as an easier script to write for copying Latin texts, starting with the Carolingian minuscule (including all the Latin letters except v and w). These were quickly adopted for writing other languages.
The first Old English alphabet was the Runic futhorc. Around the seventh century, monks who copied down the surviving works started using a modified Latin script, adding wynns, thorns, and eths. A wynn is a Runic letter that represents the W sound: Ƿ and ƿ. A thorn is also a Runic letter that represents our unvoiced TH sound as in “thin”: Þ and þ. An eth is a Latin D or d with horizontal bars that represents our voiced TH sound as in “then”: Ð and ð.
The first Aleut alphabet was based on the Russian Cyrillic; the modern Aleut alphabet is based on the Latin alphabet. The short vowels are i, u, and a; the long vowels are doubled: ii, uu, and aa. Of the consonants, only two represent a different sound from English, in particular, d, pronounced like an ð, and q, pronounced like a k but farther back in the throat. Five consonants represent sounds that are not in English: hy, g, ĝ, x, x̂. hy is a voiceless y sound, like y and h pronounced together. g is a voiced velar fricative. Unlike the g in girl, the air is not stopped. ĝ is a voiced uvular fricative, like g but farther back in the throat. x is a voiceless velar fricative, like the ch in German ach. x̂ is a voiceless uvular fricative, similar to x but farther back in the throat.
