^ ابAncient 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.
^ ابپتٹثجچIn 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.
^ ابپت⟨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].
^ ابپIn Ancient Greek, a diphthong before a vowel was realised as a vowel and a double semivowel sequence: [jj, ww].
^ ابپتIn 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].
^ ابپIn 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].
^ ابپتٹثجچحخIn 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.
^ ابپتIn 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].
^ ابپIn 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⟩.

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).
