often in ordinary conversation, during a discussion of various familiar people, we bow their names, not really thinking about the fact, and they are inclined at all.And if in friendly conversation is not so important, then, for example, in business documents such nuances just need to pay attention.There are certain rules of declension of names in Russian.
To avoid confusion, it is worth recalling the curriculum of the Russian language, including the study of cases.Take the example of a standard Russian surname Sidorov and it will decline as the masculine and feminine in:
nominative (who?) - Ford (m) Sidorova (f);
genitive (who?) - Sidorova (m) Sidorova (f);
Dative (who?) - Sidorov (m) Sidorova (f);
accusative (who?) - Sidorova (m), Sidorov (f);
Instrumental (by whom?) - Sidorov (m) Sidorova (f);
Prepositional (for whom?) - About Sidorov (m) of Sidorova (f).
Names like aforesaid, the easiest way to decline.But there are names that do not have a suffix, such as Mishka, Lanovoi, Tolstoy, Armour.
Terms declination names of this type are the same as adjectives, that is correct then write: Lanovoi, Lanovoi, Lanovoy, Lanovoi, Lanovym about lans.The feminine surname will sound like Lanovaya, thick, armor and so on. N. As adjectives, lean and surnames ending in -ski, -tsky, -skoy, -tskoy, -ev, -in, -yn, Female.
If among your friends is a man by the name of Smooth, Cheremnyh, Small, and so on. N., Remember that this is the name of a frozen form, which does not bow.Also, the rules prohibit the names declination decline the names of foreign origin ending in -their, -u, -s, -s.Do not lean, such that end in -yago, -ago.Simply put, the typical names of Russian origin should decline as the adjectives, and atypical and foreign - like nouns.
However, there are names ending in -o.For example, Shevchenko, Prikhodko, Andrei Makarenko.In this case, the rules of declension of male names, as well as women with the end of a voice that such names are not inclined either in the singular or plural.Also, do not lean female names ending with th, -b, or consonant.This is the end of zero, lean and such names can be only if you belong to a man.For example: "Give it to Vladimir Vlasyuk" and "Pass it Natalia Vlasyuk" or "Call Sergei Matskevich" and "Invite Veronica Mackiewicz."
If male surname ending in -a or th (pan, headache, Maiboroda), the rules allow you to change the names of declination end.For example, Bob Soroka, Soroca Vasya, Vasya forty Vasya Soroka and so on. N.
