English alphabet
The names of the letters are rarely spelled out, except when used in compound words (for example tee-shirt, deejay, emcee, okay, aitchless, etc.), derived forms (for example exed out, effing, to eff and blind, etc.), and in the names of objects named after letters (for example em (space) in printing and wye (junction) in railroading). The forms listed below are from the Oxford English Dictionary. Vowels stand for themselves, and consonants usually have the form consonant + ee or e + consonant (e.g. bee and ef). The exceptions are the letters aitch, jay, kay, cue, ar, ess (but es- in compounds ), wye, and zed. Plurals of consonants end in -s (bees, efs, ems) or, in the cases of aitch, ess, and ex, in -es (aitches, esses, exes). Plurals of vowels end in -es (aes, ees, ies, oes, ues); these are rare. Of course, 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.)
