form for the third-person pronoun which already occurred in late Proto-Slavic, standard literary Bulgarian (like Old Church Slavonic) does not use the Slavic "on-/ov-" as base forms like on, ona, ono, oni (he, she, it, they), and ovaj, ovde (this, here), but uses "to-/t-"based pronouns like toy, tya, to, te, and tozi, tuk (it only retains onzi – "that" and its derivatives). Western Bulgarian dialects and Macedonian have "ov-/on-" pronouns, and sometimes use them interchangeably. All dialects of Serbo-Croatian contain the concept of "any" – e.g. Serbian neko "someone"; niko "no one"; iko "anyone". All others lack the last, and make do with some- or no- constructions instead. Divisions within Western dialects While Serbian, Bosnian and Croatian Shtokavian dialects have basically the same grammar, its usage is very diverse. While all three languages are relatively highly inflected, the further east one goes the more likely it is that analytic forms are used – if not spoken, at least in the written language. A very basic example is: Croatian – hoću ići – "I want – to go" Serbian – hoću da idem – "I want – that – I go" Slovene has retained the proto-Slavic dual number (which means that it has nine personal pronouns in the third person) for both nouns and verbs. For example: nouns: volk (wolf) → volkova (two wolves) → volkovi (some wolves) verbs: hodim (I walk) → hodiva (the two of us walk) → hodimo (we walk) Divisions within Eastern dialects In Macedonian, the perfect is largely based on the verb "to have" (as in other Balkan languages like Greek and Albanian, and in English), as opposed to the verb "to be", which is used as the auxiliary in all other Slavic languages (see also Macedonian verbs): Macedonian – imam videno – I have seen (imam – "to have") Bulgarian – vidyal sum – I have seen (sum – "to be") In Macedonian there are three types of definite article (base definite form, definite noun near the speaker and definite noun far from the speaker). дете (dete, 'а child') детето (deteto, 'the child') детево (detevo, 'this child [near me]') детено (deteno, 'that child [over there]') Writing systems Languages to the west of Serbia use the Latin script, whereas those to the east and south use Cyrillic. Serbian officially uses the Cyrillic script, though commonly Latin and Cyrillic are used equally. Most newspapers are written in
