Editing Digraph (orthography) (section)

===Greek===
[[Modern Greek]] has the following digraphs:
*''αι'' (''ai'') represents {{IPA|/e̞/}}
*''ει'' (''ei'') represents {{IPA|/i/}}
*''οι'' (''oi'') represents {{IPA|/i/}}
*''ου'' (''oy'') represents {{IPA|/u/}}
*''υι'' (''yi'') represents {{IPA|/i/}}

They are called "diphthongs" in [[Greek language|Greek]]; in classical times, most of them represented [[diphthong]]s, and the name has stuck.

*''γγ'' (''gg'') represents {{IPA|/ŋɡ/}} or {{IPA|/ɡ/}}
*''τσ'' (''ts'') represents the affricate {{IPA|/ts/}}
*''τζ'' (''tz'') represents the affricate {{IPA|/dz/}}
*Initial ''γκ'' (''gk'') represents {{IPA|/ɡ/}}
*Initial ''μπ'' (''mp'') represents {{IPA|/b/}}
*Initial ''ντ'' (''nt'') represents {{IPA|/d/}}

[[Ancient Greek]] also had the "diphthongs" listed above although their pronunciation in ancient times is disputed. In addition, Ancient Greek also used the letter γ combined with a velar stop to produce the following digraphs:

*''γγ'' (''gg'') represents {{IPA|/ŋɡ/}}
*''γκ'' (''gk'') represents {{IPA|/ŋɡ/}}
*''γχ'' (''gkh'') represents {{IPA|/ŋkʰ/}}

[[Tsakonian language|Tsakonian]] has a few additional digraphs:
*''ρζ'' (''rz'') {{IPA|/ʒ/}} (historically perhaps a [[fricative trill]])
*''κχ'' (''kkh'') represents {{IPA|/kʰ/}}
*''τθ'' (''tth'') represents {{IPA|/tʰ/}}
*''πφ'' (''pph'') represents {{IPA|/pʰ/}}
*''σχ'' (''skh'') represents {{IPA|/ʃ/}}
In addition, [[palatal consonant]]s are indicated with the vowel letter ''ι'', which is, however, largely predictable. When {{IPA|/n/}} and {{IPA|/l/}} are not palatalized before ''ι'', they are written ''νν'' and ''λλ''.

In [[Bactrian language|Bactrian]], the digraphs ''ββ'', ''δδ'', and ''γγ'' were used for {{IPA|/b/}}, {{IPA|/d/}}, and {{IPA|/ŋg/}} respectively.
