The Greek eta '?' in Archaic Greek alphabets still represented /h/ (later on it came to represent a long vowel, /?:/). In this context, the letter eta is also known as heta to underline this fact. Thus, in the Old Italic alphabets, the letter heta of the Euboean alphabet was adopted with its original sound value /h/.
While Etruscan and Latin had /h/ as a phoneme, almost all Romance languages lost the sound--Romanian later re-borrowed the /h/ phoneme from its neighbouring Slavic languages, and Spanish developed a secondary /h/ from /f/, before losing it again; various Spanish dialects have developed [h] as an allophone of /s/ or /x/ in most Spanish-speaking countries, and various dialects of Portuguese use it as an allophone of /?/. 'H' is also used in many spelling systems in digraphs and trigraphs, such as 'ch', which represents /t?/ in Spanish, Galician, Old Portuguese and English, /?/ in French and modern Portuguese, /k/ in Italian, French and English, /x/ in German, Czech, Polish, Slovak, one native word of English and a few loanwords into English, and /ç/ in German.
For most English speakers, the name for the letter is pronounced as and spelled "aitch" or occasionally "eitch". The pronunciation and the associated spelling "haitch" is often considered to be h-adding and is considered nonstandard in England. It is, however, a feature of Hiberno-English, as well as scattered varieties of Edinburgh, England, and Welsh English and Australia.
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 /he?t?/ 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.
The haitch pronunciation of h has spread in England, being used by approximately 24% of English people born since 1982, 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.
Authorities disagree about the history of the letter's name. The Oxford English Dictionary says the original name of the letter was ['aha] in Latin; this became ['aka] in Vulgar Latin, passed into English via Old French [at?], and by Middle English was pronounced [a:t?]. 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.
In English, ⟨h⟩ occurs as a single-letter grapheme (being either silent or representing the voiceless glottal fricative and in various digraphs, such as ⟨ch⟩ , , , or ), ⟨gh⟩ (silent, /?/, /k/, /p/, or /f/), ⟨ph⟩ (/f/), ⟨rh⟩ (/r/), ⟨sh⟩ , ⟨th⟩ ( or ), ⟨wh⟩ (). The letter is silent in a syllable rime, as in ah, ohm, dahlia, cheetah, pooh-poohed, as well as in certain other words (mostly of French origin) such as hour, honest, herb (in American but not British English) and vehicle (in certain varieties of English). Initial /h/ is often not pronounced in the weak form of some function words including had, has, have, he, her, him, his, and in some varieties of English (including most regional dialects of England and Wales) it is often omitted in all words (see '⟨h⟩'-dropping). It was formerly common for an rather than a to be used as the indefinite article before a word beginning with /h/ in an unstressed syllable, as in "an historian", but use of a is now more usual (see English articles § Indefinite article). In English, The pronunciation of ⟨h⟩ as /h/ can be analyzed as a voiceless vowel. That is, when the phoneme /h/ precedes a vowel, /h/ may be realized as a voiceless version of the subsequent vowel. For example the word ⟨hit⟩, /h?t/ is realized as [t]. H is the eighth most frequently used letter in the English language (after S, N, I, O, A, T, and E), with a frequency of about 4.2% in words.
In the German language, the name of the letter is pronounced /ha:/. Following a vowel, it often silently indicates that the vowel is long: In the word erhöhen ('heighten'), the second ⟨h⟩ is mute for most speakers outside of Switzerland. In 1901, a spelling reform eliminated the silent ⟨h⟩ in nearly all instances of ⟨th⟩ in native German words such as thun ('to do') or Thür ('door'). It has been left unchanged in words derived from Greek, such as Theater ('theater') and Thron ('throne'), which continue to be spelled with ⟨th⟩ even after the last German spelling reform.
In Spanish and Portuguese, ⟨h⟩ ("hache" in Spanish, pronounced ['at?e], or agá in Portuguese, pronounced [a'?a] or [?'?a]) is a silent letter with no pronunciation, as in hijo ['ixo] ('son') and húngaro ['a?u] ('Hungarian'). The spelling reflects an earlier pronunciation of the sound /h/. It is sometimes pronounced with the value [h], in some regions of Andalusia, Extremadura, Canarias, Cantabria and the Americas in the beginning of some words. ⟨h⟩ also appears in the digraph ⟨ch⟩, which represents /t?/ in Spanish and northern Portugal, and /?/ in oral traditions that merged both sounds (the latter originarily represented by ⟨x⟩ instead) e.g. in most of the Portuguese language and some Spanish-speaking places, prominently Chile, as well as ⟨nh⟩ /?/ and ⟨lh⟩ /?/ in Portuguese, whose spelling is inherited from Occitan.
In French, the name of the letter is written as "ache" and pronounced /a?/. The French orthography classifies words that begin with this letter in two ways, one of which can affect the pronunciation, even though it is a silent letter either way. The H muet, or "mute" ⟨h⟩, is considered as though the letter were not there at all, so for example the singular definite article le or la, which is elided to l' before a vowel, elides before an H muet followed by a vowel. For example, le + hébergement becomes l'hébergement ('the accommodation'). The other kind of ⟨h⟩ is called h aspiré ("aspirated '⟨h⟩'", though it is not normally aspirated phonetically), and does not allow elision or liaison. For example in le homard ('the lobster') the article le remains unelided, and may be separated from the noun with a bit of a glottal stop. Most words that begin with an H muet come from Latin (honneur, homme) or from Greek through Latin (hécatombe), whereas most words beginning with an H aspiré come from Germanic (harpe, hareng) or non-Indo-European languages (harem, hamac, haricot); in some cases, an orthographic ⟨h⟩ was added to disambiguate the [v] and semivowel [?] pronunciations before the introduction of the distinction between the letters ⟨v⟩ and ⟨u⟩: huit (from uit, ultimately from Latin octo), huître (from uistre, ultimately from Greek through Latin ostrea).
In Italian, ⟨h⟩ has no phonological value. Its most important uses are in the digraphs 'ch' /k/ and 'gh' /?/, as well as to differentiate the spellings of certain short words that are homophones, for example some present tense forms of the verb avere ('to have') (such as hanno, 'they have', vs. anno, 'year'), and in short interjections (oh, ehi).
In Hungarian, the letter has five independent pronunciations, perhaps more than in any other language, with an additional three uses as a productive and non-productive member of a digraph. H may represent /h/ as in the name of the Székely town Hargita; intervocalically it represents /?/ as in "tehéz"; it represents /x/ in the word "doh"; it represents /ç/ in "ihlet"; and it is silent in "Cseh". As part of a diphthong, it represents, in archaic spelling, /t/ with the letter C as in the name "Széchényi; it represents, again, with the letter C, /x/ in "pech" (which is pronounced [p?x]); in certain environments it breaks palatalization of a consonant, as in the name "Horthy" which is pronounced [h?rti] (without the intervening H, the name "Horty" would be pronounced [h?rc]); and finally, it acts as a silent component of a diphthong, as in the name "Vargha", pronounced [v?rg?].
In Irish, ⟨h⟩ is not considered an independent letter, except for a very few non-native words, however ⟨h⟩ placed after a consonant is known as a "séimhiú" and indicates lenition of that consonant; ⟨h⟩ began to replace the original form of a séimhiú, a dot placed above the consonant, after the introduction of typewriters.
In most dialects of Polish, both ⟨h⟩ and the digraph ⟨ch⟩ always represent /x/.
In Basque, during the 20th century it was not used in the orthography of the Basque dialects in Spain but it marked an aspiration in the North-Eastern dialects. During the standardization of Basque in the 1970s, the compromise was reached that h would be accepted if it were the first consonant in a syllable. Hence, herri ("people") and etorri ("to come") were accepted instead of erri (Biscayan) and ethorri (Souletin). Speakers could pronounce the h or not. For the dialects lacking the aspiration, this meant a complication added to the standardized spelling.
As a phonetic symbol in the International Phonetic Alphabet (IPA), it is used mainly for the so-called aspirations (fricative or trills), and variations of the plain letter are used to represent two sounds: the lowercase form ⟨h⟩ represents the voiceless glottal fricative, and the small capital form ⟨?⟩ represents the voiceless epiglottal fricative (or trill). With a bar, minuscule ⟨?⟩ is used for a voiceless pharyngeal fricative. Specific to the IPA, a hooked ⟨?⟩ is used for a voiced glottal fricative, and a superscript ⟨?⟩ is used to represent aspiration.
