DH

Dh is a digraph formed by the Latin letters D and h. It is not a distinct character of the Latin alphabet, but a two-letter combination used in various writing systems and transliteration schemes to represent different sounds.

Indic transliteration: In the transliteration of Devanagari and related scripts, the character ध is commonly rendered as "dh". The consonant denotes an aspirated voiced stop, typically realized as a dental or alveolar /d̪ʱ/ or /dʱ/ depending on language, and carries the inherent vowel in syllables such as "dha." In standard schemes like IAST and ISO 15919, "dh" appears as part of syllables (e.g., dha, dhara).

Other transliteration contexts: In some scholarly contexts, "dh" is used to approximate the voiced dental fricative /ð/ (as in English "this") in transliterations where the target language has that sound but the orthography uses the Latin alphabet only. The exact sound value of "dh" therefore varies by language and transliteration system.

General usage: Dh functions as a common digraph in many languages, representing a variety of sounds depending on phonology and orthographic history. It is not a separate letter in the Latin alphabet, but a sequence of two letters that may appear at the start, middle, or end of words.

Computing and typography: In digital text, "Dh" is simply a case pair of two letters. There is no unique Unicode character for "Dh"; case forms follow standard Latin capitalization rules.
