H, or h, is the eighth letter of the Latin alphabet, used in the modern English alphabet, including the alphabets of other western European languages and others worldwide. Its name in English is aitch (pronounced /eɪtʃ/, plural aitches), or regionally haitch /heɪtʃ/.[1]
For most English speakers, the name for the letter is pronounced as /eɪtʃ/ and spelled "aitch"[1] or occasionally "eitch". The pronunciation /heɪtʃ/ and the associated spelling "haitch" is often considered to be h-adding and is considered non-standard in England.[2] It is, however, a feature of Hiberno-English,[3] and occurs sporadically in various other dialects.
The perceived name of the letter affects the choice of indefinite article before initialisms beginning with H: for example "an H-bomb" or "a H-bomb". The pronunciation /heɪtʃ/ may be a hypercorrection formed by analogy with the names of the other letters of the alphabet, most of which include the sound they represent.[4]
The haitch pronunciation of h has spread in England, being used by approximately 24% of English people born since 1982,[5] and polls continue to show this pronunciation becoming more common among younger native speakers. Despite this increasing number, the pronunciation without the /h/ sound is still considered to be standard in England, although the pronunciation with /h/ is also attested as a legitimate variant.[2] In Northern Ireland, the pronunciation of the letter has been used as a shibboleth, with Catholics typically pronouncing it with the /h/ and Protestants pronouncing the letter without it.[6]
Authorities disagree about the history of the letter's name. The Oxford English Dictionary says the original name of the letter was [ˈaha] in Latin; this became [ˈaka] in Vulgar Latin, passed into English via Old French [atʃ], and by Middle English was pronounced [aːtʃ]. The American Heritage Dictionary of the English Language derives it from French hache from Latin haca or hic. Anatoly Liberman suggests a conflation of two obsolete orderings of the alphabet, one with H immediately followed by K and the other without any K: reciting the former's ..., H, K, L,... as [...(h)a ka el ...] when reinterpreted for the latter ..., H, L,... would imply a pronunciation [(h)a ka] for H.[7]
The original Semitic letter Heth most likely represented the voiceless pharyngeal fricative (ħ). The form of the letter probably stood for a fence or posts.
