From Wikipedia, the free encyclopedia
A
pentagraph
(from the
Greek
:
π?ντε
,
pente
, "five" and γρ?φω,
graph?
, "write") is a sequence of five letters used to represent a single sound (phoneme), or a combination of sounds, that do not correspond to the individual values of the letters.
[1]
In
German
, for example, the pentagraph
tzsch
represents the
[t?]
sound of the English
digraph
ch,
and indeed is found in the English word
Nie
tzsch
ean
.
Irish
has several pentagraphs.

In
Cyrillic
used for
languages of the Caucasus
, there are a couple five-letter sequences used for 'strong' (typically transcribed in the IPA as geminate, and doubled in Cyrillic) labialized consonants. Since both features are predictable from the orthography, their pentagraph status is dubious.
The pentagraph
⟨
ххь?в
⟩
is used in
Archi
for
[χː??]
:
[2]
a
labialized
⟨ххь?⟩
[χː?]
, which is the '
strong
' counterpart of the
pharyngealized
voiceless uvular fricative
(
[χ?]
), written using the trigraph
⟨хь?⟩
, whose graph is in turn an unpredictable derivation of
⟨х⟩
(
[χ]
) and thus a true trigraph. It occurs, for example, in the word
ххьIв
елтIбос
("rummage through someone else's things").
