A
unicase or
unicameral alphabet is one that has no
case for its letters.
Persian,
Kannada,
Tamil,
Arabic,
Old Hungarian,
Hebrew,
Georgian and
Hangul are unicase alphabets, while (modern)
Latin,
Greek,
Cyrillic and
Armenian are
bicameral, as they have two cases for each letter,
e.g., B/b, Β/β, Б/б, Բ/բ. Individual characters can also be called unicameral if they are used as letters with a generally bicameral alphabet but have only one form for both cases; for example,
ʻokina (), used in Polynesian languages, and
glottal stop () as used in
Nootka.
