List of Latin-script trigraphs

A number of trigraphs are found in the Latin script, most of these used especially in Irish orthography.

A

⟨aai⟩ is used in Dutch to write the sound /aːi̯/.

⟨abh⟩ is used in Irish to write the sound /əu̯/, or in Donegal, /oː/, between broad consonants.

⟨adh⟩ is used in Irish to write the sound /əi̯/, or in Donegal, /eː/, between broad consonants, or an unstressed /ə/ at the end of a word.

⟨aei⟩ is used in Irish to write the sound /eː/ between a broad and a slender consonant.

⟨agh⟩ is used in Irish to write the sound /əi̯/, or in Donegal, /eː/, between broad consonants.

Greek language

Greek or Hellenic (Modern Greek: ελληνικά [eliniˈka], elliniká, "Greek", ελληνική γλώσσα [eliniˈci ˈɣlosa], ellinikí glóssa, "Greek language") is an independent branch of the Indo-European family of languages, native to the southern Balkans, the Aegean Islands, western Asia Minor, parts of northern and Eastern Anatolia and the South Caucasus, southern Italy, Albania and Cyprus. It has the longest documented history of any Indo-European language, spanning 34 centuries of written records. Its writing system has been the Greek alphabet for the majority of its history; other systems, such as Linear B and the Cypriot syllabary, were used previously. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic and many other writing systems.

The Greek language holds an important place in the histories of Europe, the more loosely defined Western world, and Christianity; the canon of ancient Greek literature includes works of monumental importance and influence for the future Western canon such as the epic poems Iliad and Odyssey. Greek was also the language in which many of the foundational texts of Western philosophy, such as the Platonic dialogues and the works of Aristotle, were composed; the New Testament of the Christian Bible was written in Koiné Greek. Together with the Latin texts and traditions of the Roman world, the study of the Greek texts and society of antiquity constitutes the discipline of Classics.
