Macedonian and Bulgarian
These two languages are quite similar. They belong to "Eastern South Slavic" group. The most striking feature is that they lost cases, there are only basic forms for personal pronouns (nom., acc., dat.) — and the result is a grammar similar to Spanish and Italian. For instance (Macedonian):
Jas ja imam pročitano kniga-ta. I it have read book-the "I have read the book."
The grammar is very similar to English in some aspects: past is formed with "have" and passive participle, there is a definite article (however, appended to a noun), etc. Macedonian and Bulgarian are normally written in Cyrilic script only, but they have some different symbols, and both differ from Serbian Cyrillic. The "final L rule" is turned off. "Yat" is always e in Macedonian, but often ja in Bulgarian -- hence the name "yat"! "Yers" are split to different vowels (Macedonian : Bulgarian):
[under construction]
десет deset "ten" {deset}
име ime "name" {ime}
месо meso "meat" {meso}
пет pet "five" {pet}
се se acc. "self" {se}
млеко mleko : мляко mljako "milk" {mlijëko}
град grad "city, town" {grad}
среда sreda : сряда srjada "Wednesday" {srijëda}
тело telo : тяло tjalo "body" {tijëlo}
сон son : сън sən "dream" {sän}
штица štica "plank" {däska}
ветер veter : вятър vjatər "wind" {vjëtär}
.. "glass" {stäklo}
Old Church Slavic is a language that was spoken 1000 years ago in today's Bulgaria, that was used to translate some Christian books. That language has all complex features we have seen in Croatian, the dual from Slovenian and much more. It helps to explain many features of today Slavic languages. It had 11 distinct vowels, for example. It's relation to Croatian is in a way what Latin is to today's Spanish.
Russian
Russian is written in Cyrillic script only, but of course it's different than Serbian, Bulgarian or Macedonian Cyrillic! Russian has a special way of writing "soft" consonants (like Croatian lj) — in my opinion, as complicated as possible. To illustrate the system, I will show declension of student "student" and učitelj "teacher" in Croatian and Russian. In both languages they have the same meaning, they are masculine animate in both languages. The Russian declension in singular is quite similar to Standard Croatian (no vocative but a separate locative case), and even closer to Čakavian or Kajkavian:
case Croatian Russian Croatian Russian nom. student stud’ent студент učitelj učit’el’ учитель acc. studenta stud’enta студента učitelja učit’el’a учителя dat. studentu stud’entu студенту učitelju učit’el’u учителю loc. stud’ent’e студенте učit’el’e учителе ins. studentom stud’entom студентом učiteljem učit’el’em учителем
Can you see it? Russian writes the "soft" l (= Croatian lj) as ль, but if there's a vowel after it, Russian uses special signs: l’a = l-’a = ля. Other "softening+vowel" combinations are е (’e), и (’i), ё (’o) and ю (’u).
"Non-softening" vowels are а (a), э (e), ы (i), о (o), and у (u). Russian has a sign for j (й) but uses it only at the end of a word or before other consonant; at other positions, the "combination vowels" are used. Even worse, some consonants cannot be softened (e.g č) so for instance чи is just pronounced či, and there's even spelling ночь, pronounced just noč and meaning of course "night" (Croatian noć).
Yet another complication is that Russian vowels are pronounced differently in various positions, depending on the stress; its position is roughly as in Čakavian. For instance Russian ona "she" looks identical to the Croatian word of the same meaning, but since the stress is on the last syllable — and that's not indicated in Russian spelling — it's pronounced actually as /anà/! This is a famous phenomenon called akanje. As in Čakavian, the stress often moves from case to case, and so the pronunciation changes from case to case... no wonder I understand written Russian much better than spoken, despite the Cyrillic!
Russian verbs in 1st pers. present mostly end in -u, while in Croatian there's only two (hoću, mogu). Otherwise, the system is close to Kajkavian: the future is budu + inf., or just a perf. verb, the conditional verb is always just bi. Strangely, Russian does not use the verb sam, bio but it's somehow implied:
Я студент. Ja stud’ent. "I am a student." {Ja säm student.}
Ты читал книгу. Ti čital kn’igu. "You were reading a book." {Ti si čitao knjigu.}
As you see, the "Final L Rule" is turned off in Russian. There are 5 vowels. 'Yat' is always e, and 'yer' can be either o or e. In some circumstances Russian ja (spelled of course as я) corresponds to Croatian e. Croatian sequences l/r + a/yat + consonant have additional vowels in Russian (Croatian equivalents are in curly braces {...}, all have the same meaning).
десять d’es’at’ "ten" {deset}
имя im’a "name" {ime}
мясо m’aso "meat" {meso}
пять p’at’ "five" {pet}
ся s’a acc. "self" {se}
молоко moloko "milk" {mlijëko}
город gorod "city, town" {grad}
среда sr’eda "Wednesday" {srijëda}
тело t’elo "body" {tijëlo}
сон son "dream" {sän}
доска doska "plank" {däska}
ветер v’et’er "wind" {vjëtär}
стекло st’eklo "glass" {stäklo}
There are other differences, for instance there are no short pronouns in Russian. Some prepositions are different, etc. So much about it.
Other Slavic Languages
Belarusian and Ukrainian languages are similar to Russian, but different a bit. They both use Cyrillic script only — of course, sightly different than the Russian one. A substantial part of population of Belarus and Ukraine speaks Russian as their first language.
Czech has a spelling similar to Croatian (actually, Croats "borrowed" it from Czechs) but is more complicated in some aspects of grammar. For instance, Croatian distinguishes nouns and adjectives with "soft" endings (on č, ć, đ, lj, š, nj, lj, ž, j) and "hard" endings (anything else) only by occasional -e- vs. -o- in endings. Not so in Czech. There are quite different patterns for nouns ending on a soft or hard consonant:
case hard soft ma mi n ma mi n nom. sg. - -o - -e acc. sg. -a - -e - dat. sg. -u, -ovi -u -i, -ovi -i loc. sg. -u, -e, -ě gen. sg. -a -u, -a -a -e ins. sg. -em
I have omitted patterns for a- and i-nouns for brevity. You see, it's more complicated than Croatian.
Czech words are always stressed on the first syllable: marks á, ó etc. mean long vowels, a distinction that's really important to Czech. Some sounds have more than one spelling for historic reasons: i can be also spelled y, ú can be also spelled ů. There are special sounds spelled as d', ň, ř and t', in addition to Croatian-like č, š and ž.
There's also a "vowel-like" l in words like pln "full" {pun} and vlk "wolf" {vuk}, in addition to vowel-like r that's also shared by Croatian.
Destiny of 'yat' and 'yer' is not simple at all in Czech, as illustrated by the following words. All have the same meanings in Croatian and Czech except hrad "castle" vs. grad "city".
deset "ten" {deset}
jméno "name" {ime}
maso "meat" {meso}
pět "five" {pet}
se acc. "self" {se}
mléko "milk" {mlijëko}
hrad "castle" {grad "city"}
středa "Wednesday" {srijëda}
tělo "body" {tijëlo}
sen "dream" {sän}
deska "plank" {däska}
vítr "wind" {vjëtär}
sklo "glass" {stäklo}
