Benjamin Franklin's phonetic alphabet as follows: Franklin's proposed alphabet included seven letters to represent vowels. This set consisted of two new letters, in addition to five letters from the existing English alphabet: a, e, i, o, u. The first new letter was a formed as a ligature of the letters o and a, and used to represent the sound (as written in IPA). The second, ɥ, was used for . Franklin proposed the use of doubled letters to represent what he called long vowels, represented by modern phonemes thus: as the long-vowel variant for (or, in his notation, "cɩcɩ" versus "cɩ"), for ("ee" versus
English alphabet and "ex", in "-es" ("aitches, esses, exes"). Plurals of vowels end in "-es" ("aes, ees, ies, oes, ues"); these are rare. All letters may stand for themselves, generally in capitalized form ("okay" or "OK", "emcee" or "MC"), and plurals may be based on these ("aes" or "As", "cees" or "Cs", etc.") The names of the letters are for the most part direct descendants, via French, of the Latin (and Etruscan) names. (See Latin alphabet: Origins.) The regular phonological developments (in rough chronological order) are: The novel forms are "aitch", a regular development of Medieval Latin "acca"; "jay", a new letter
