In Italian H has no real phonological value. It is rather a diacritic grapheme. The most important uses are to differentiate certain short
words,for example some present tenseforms of the verb avere “tohave” (hanno = they have, whereas anno = year), in short interjections
(oh, ehi),and in the digraphs ch/k/ and gh /ɡ/. Some languages, includingEnglish, Czech, Slovak, Hungarian and Finnish, use H as
abreathy voiced glottal fricative [ɦ], often as an allophone of otherwise voiceless /h/ in a voiced environment. In Ukrainian and
Belarusian, when written inthe Latin alphabet, H is also commonlyused for /ɦ/, normally written with the Cyrillic letter Г. (Note the
difference from Russianpronunciation and romanisation.) In Irish H after a consonant indicates lenition of that consonant; it is known
as a séimhiú.
