Unicase
From Wikipedia, the free encyclopedia
A unicase alphabet is one that has no case for its letters. Arabic, Hebrew and Georgian are unicase alphabets, while Latin, Greek, Cyrillic and Armenian have two cases for each letter (e.g. A/a, B/b, C/c etc). Rules for case usage vary--apart from the general rule of capitalizing the first word of the sentence, each language has its own rules (e.g. English "Monday" vs. French "lundi", or the German rule of capitalizing every noun).
All alphabets with case were once unicase. Latin, for example, used to be written without case in imperial Roman times; it was only later that scribes developed a new set of symbols for running text, which became the lower case of the Latin alphabet, and the letterforms of Ancient Rome became what we now call capitals.
The Georgian alphabet, in contrast, went the other way: the medieval Georgian alphabet with its two cases gave in to a unicase set. The ecclesiastical form of the Georgian alphabet, Khutsuri, had an upper case called Asomtavruli (like the Ancient Roman capitals) and a lower case called Nuskhuri (like the medieval Latin scribal forms). Out of Nuskhuri came a secular alphabet called Mkhedruli, which is the unicase Georgian alphabet in use today.
A unicase version of the Latin alphabet was proposed by Michael Mann and David Dalby in 1982 as a variation of the Niamey African Reference Alphabet. This version has apparently never been actively used.
