unvoiced in normal speech in such clusters): predstava (show) odšteta (damages) Only a few words are intentionally "misspelled", mostly in order to resolve ambiguity: šeststo (six hundred)pronounced šesto (to avoid confusion with "šesto" [sixth], pronounced the same) prstni (adj., finger)pronounced prsni (to avoid confusion with "prsni" [adj., chest]), differentiated by tone in some areas (where the short rising tone contrasts with the short falling tone). Writing systems Through history, this language has been written in a number of writing systems: Glagolitic alphabet, chiefly in Croatia. Bosančica, Arebica (mostly in Bosnia and Herzegovina). Cyrillic script. various modifications of the Latin and Greek alphabets. The oldest texts since the 11th century are in Glagolitic, and the oldest preserved text written completely in the Latin alphabet is , from 1345. The Arabic alphabet had been used by Bosniaks; Greek writing is out of use there, and Arabic and Glagolitic persisted so far partly in religious liturgies. Today, it is written in both the Latin and Cyrillic scripts. Serbian and Bosnian variants use both alphabets, while Croatian uses the Latin only. Latin script has become more and more popular in Serbia, as it is easy to input on phones and computers. The Serbian Cyrillic alphabet was revised by Vuk Stefanović Karadžić in the 19th century. The Croatian Latin alphabet () followed suit shortly afterwards, when Ljudevit Gaj defined it as standard Latin with five extra letters that had diacritics, apparently borrowing much from Czech, but also from Polish, and inventing the unique digraphs , and . These digraphs are represented as , and respectively in the , published by the former Yugoslav Academy of Sciences and Arts in Zagreb. The latter digraphs, however, are unused in the literary standard of the language. All in all, this makes Serbo-Croatian the only Slavic language to officially use both the Latin and Cyrillic scripts, albeit the Latin version is more commonly used. In both cases, spelling is phonetic and spellings in the two alphabets map to each other one-to-one: The digraphs Lj, Nj and Dž represent distinct phonemes and are considered to be single letters. In crosswords, they are put into a single square, and in sorting, lj follows l and nj follows n, except in a few words where the individual letters are pronounced separately. For instance, "to outlive" is composed of the prefix "out, over" and the verb "to live". The Cyrillic alphabet avoids such
