It provides a set of symbols to represent the pronunciation of Greek in Wikipedia articles, and example words that illustrate the sounds that correspond to them. Integrity must be maintained between the key and the transcriptions that link here. Changes should reflect consensus; especially if the conventions of this key are already in wide use, any substantive change to it should be discussed on the talk page first so as not to create discrepancies between the key and transcriptions.
^ abAncient Greek had geminate consonants, pronounced longer than single ones, which may be transcribed by a double consonant letter ⟨ss⟩ or the length symbol ⟨sː⟩. Modern Standard Greek does not have geminate consonants, but some nonstandard dialects do.
^ abcdefghIn Modern Greek, ⟨κ; γκ, γγ; γ; χ⟩ are pronounced as palatal [c, ɟ, ʝ, ç] before the front vowels [e i], and velar [k, g, ɣ, x] in other cases.
^ abcd⟨ζ⟩ represented the cluster [zd] in Classical Attic, but it represents [z] in Modern Greek. In both Ancient and Modern Greek, ⟨σ⟩ is pronounced as voiced [z] before a voiced consonant, and ⟨ξ, ψ⟩ represent [ks ps].
^ abcIn Ancient Greek, a diphthong before a vowel was realised as a vowel and a double semivowel sequence: [jj, ww].
^ abcdIn Modern Greek, ⟨μπ, ντ, γκ, γγ⟩ are pronounced as prenasalised voiced stops [mb, nd, ɲɟ, ŋɡ] or voiced stops without nasalisation [b, d, ɟ, ɡ].
^ abcIn Modern Greek, ⟨υ⟩, in ⟨αυ ευ ηυ⟩, is pronounced as [f] before a voiceless consonant and [v] otherwise. In Ancient Greek, ⟨αυ ευ ηυ⟩ were diphthongs [au̯ eu̯ ɛːu̯].
^The rough breathing ⟨῾⟩ represented [h] before a vowel, and the smooth breathing ⟨᾿⟩ represented the absence of [h].
^ abcdefghijIn Modern Greek, ⟨η, ῃ, ει, ι, οι, υ, υι⟩ all represent [i], but they were pronounced [ɛː, ɛːi̯, eː, ei̯, i(ː) oi̯, y(ː), yi̯] in Ancient Greek. The large number of vowel mergers into [i] is called iotacism.
^ abcdIn Modern Greek, ⟨ε, αι⟩ represent [e], and ⟨ο, ω⟩ represent [o]. In Ancient Greek, ⟨ε, ο⟩ represented [e, o], ⟨ω⟩ represented [ɔː] and ⟨αι⟩ represented the diphthong[ai̯].
^In archaic and some dialectal Greek ⟨ει⟩ represented the true diphthong [ei̯] but in inter alia Attic Greek, [ei̯] and [eː] later merged into the latter hence ⟨ει⟩ is a spurious diphthong, i.e. it actually represents the monophthong [eː].
^ abcIn early Ancient Greek, ⟨ᾳ, ῃ, ῳ⟩ were diphthongs, but the second element [i̯] was lost soon after the Classical period, and they merged with ⟨ᾱ, η, ω⟩.
^The symbols used here for Ancient Greek pitch accent must be added as combining characters in some cases. Place the numeric character reference after the letter that on which the accent is to be put, press "Show preview" and copy the resulting accented character. ́ is the numeric character reference for combining acute tone mark (high tone), ̌ for combining caron (rising tone), ̂ for combining circumflex (falling tone).
