This is a list of tetragraphs in the Latin script. These are most common in Irish orthography. For Cyrillic tetragraphs, see tetragraph#Cyrillic script.

Irish

Used between two velarized ("broad") consonants:

adha⟩ and ⟨agha⟩ are used for [əi̯] (in Donegal, [eː]).
abha⟩, ⟨amha⟩, ⟨obha⟩, ⟨odha⟩, ⟨ogha⟩ are used for [əu̯] (in Donegal, [oː]).
omha⟩ is used for [oː].

Used between two palatalized ("slender") consonants:

eidh⟩ and ⟨eigh⟩ are used for [əi̯].

Used between a broad and a slender consonant:

aidh⟩ and ⟨aigh⟩ are used for [əi̯] (in Donegal, [eː]).
oidh⟩ and ⟨oigh⟩ are used for [əi̯].

Used between a slender and a broad consonant:

eabh⟩ and ⟨eamh⟩ are used for [əu̯] (in Donegal, [oː]).
eadh⟩ is used for [əi̯] (in Donegal, [eː]) between a slender and a broad consonant, or for an unstressed [ə] at the end of a word.

English

English does not have many tetragraphs. However, when one of the elements in a sequence of digraphs is silent, such as may be are found in word-initial position in Greek or Russian loanwords, such cases might be confused with tetragraphs:

chth⟩ is pronounced /θ/ or /kθ/ in chthonian and related words. When not initial, as in autochthonous, it is always pronounced /kθ/.

phth⟩ is pronounced /θ/ or /fθ/ in such words as phthisis. When not initial, as in naphthol or diphthong, it is pronounced /fθ/ or with some people /pθ/.[1]

shch⟩ is used as the transcription of the Cyrillic letter Щ. It is usually read as a sequence of digraphs, /ʃ.t͡ʃ/ or /s.t͡ʃ/. However, when initial, as in shcherbakovite, the second element is silent: /ʃɜrbəˈkɒvaɪt/.

ough⟩ has ten pronunciations, in half of which the digraph gh is silent. Examples are drought, bought, though, and through.

French

illi⟩ is used to write the sound [j] in a few words such as médaillier [medaje].

In addition, trigraphs are sometimes followed by silent letters, and these sequences may be confused with tetragraphs:

cque⟩ is found for [k] in words such as "grecque" and "Mecque", where the trigraph cqu is followed by the feminine suffix e.

eaux⟩ is found for [o] when the silent plural suffix x is added to the trigraph eau.

Juǀʼhoansi

The apostrophe was used with three trigraphs for click consonants in the 1987 orthography of Juǀʼhoansi. The apostrophe is a diacritic rather than a letter in Juǀʼhoansi.

dcg’⟩ for [ᶢǀʢ]

dçg’⟩ for [ᶢǂʢ]

dqg’⟩ for [ᶢǃʢ]

dxg’⟩ for [ᶢǁʢ]

German

tsch⟩ is used for [tʃ] in a few German words.

dsch⟩ is used in German to write the sound [dʒ].

zsch⟩ is used for [tʃ] in a few German names such as Zschopau.

Hmong

There are several sequences of four letters in the Romanized Popular Alphabet that transcribe what may be single consonants, depending on the analysis. However, their pronunciations are predictable from their components. All begin with the ⟨n⟩ of prenasalization, and end with the ⟨h⟩ of aspiration. Between these is a digraph, one of ⟨dl⟩ /tˡ/, ⟨pl⟩ /pˡ/, ⟨ts⟩ /ʈ͡ʂ/, or ⟨tx⟩ /t͡s/, which may itself be predictable.

ndlh⟩ is /ndˡʱ/.

nplh⟩ is /mbˡʱ/.

ntsh⟩ is /ɳɖʐʱ/.

ntxh⟩ is /ndzʱ/.

Arrernte

Tetragraphs in Arrernte transcribe single consonants, but are largely predictable from their components.

kngw⟩ is /ᵏŋʷ/

rtnw⟩ is /ʈɳʷ/

thnw⟩ and ⟨tnhw⟩ are /ᵗ̪n̪ʷ/

tnyw⟩ is /ᶜɲʷ/

Piedmontese

Piedmontese does not have tetragraphs. A hyphen may separate ⟨s⟩ from ⟨c⟩ or ⟨g⟩, when these would otherwise be read as single sounds.

s-c⟩ and ⟨s-cc⟩ are used before front vowels for the sequence /stʃ/, to avoid confusion with the digraph ⟨sc⟩ for /ʃ/.

s-g⟩ and ⟨s-gg⟩ are similarly used for the sequence /zdʒ/.

Others

eeuw⟩ and ⟨ieuw⟩ are used in Dutch for the sounds [eːu̯] and [iːu̯]. ⟨Uw⟩ alone stands for [yːu̯], so these sequences are not predictable.

gqx’⟩ is used in the practical orthography of the Taa language, where it represents the prevoiced affricate [ɢqχʼ].

ng’w⟩ is used for [ŋʷ] in Swahili-based alphabets. However, the apostrophe is a diacritic in Swahili, not a letter, so this is not a true tetragraph.

nyng⟩ is used in Yanyuwa to write a pre-velar nasal, [ŋ̟].

s-ch⟩ is used in the Puter orthographic variety of the Romansh language (spoken in the Upper Engadin area in Switzerland) for the sequence /ʃtɕ/ (while the similar trigraph ⟨sch⟩ denotes the sounds /ʃ/ and /ʒ/).[2] It is not part of the orthography of Rumantsch Grischun, but is used in place names like S-chanf and in the Puter orthography used locally in schools again since 2011.

thsh⟩ is used in Xhosa to write the sound [tʃʰ]. It is often replaced with the ambiguous trigraphtsh⟩.
