The Russian language has preserved an Indo-European inflexional structure, although considerable adaptation has taken place.
俄语保留了印欧语系屈折语的结构，尽管有很大的改变。
Russian has a highly inflexional morphology, particularly in nominals (nouns, pronouns, adjectives and numerals). The Russian literary syntax is a combination of three elements: a Church Slavonic inheritance, a Western European style,[clarification needed] and a polished[clarification needed] vernacular foundation.
俄语具备高度的词性变化特点，特别在名词，代词，形容词，以及副词上。俄语文法是三个元素的组合，分别是教会斯拉夫的遗留语言习惯，西欧风格，以及美化后的口语白话。
名词:
名词
Nominal declension is subject to six cases – nominative, genitive, dative, accusative, instrumental, and prepositional. 名词的变格从属于六种情况，分别是主格，属格，与格，宾格，工具格，前置格。性数格。
More often than in many other Indo-European languages, Russian noun cases may supplant the use of prepositions entirely. 相比于其他印欧语言，俄语的名词的情况可能会完全取代介词的使用。
There are no definite or indefinite articles (such as the, a, an in English) in the Russian language.俄语中没有冠词，需要从语境中分辨。
The category of animacy is relevant in Russian nominal and adjectival declension.在俄语中名词与形容词的生命度对其变形有影响。
In Russian there are three declensions:[7]俄语中存在的三中变格情况：
The first declension is used for most masculine and neuter nouns.第一种用于大部分的阳性和中性名词。
The second declension is used for feminine nouns ending with -а/-я and some masculine nouns having the same form as those of feminine gender, such as па́па papa or дя́дя uncle; also, there are common-gender nouns like зади́ра tease that are masculine or feminine depending on the person to which they refer.第二种变形使用于结尾是...的阴性名词和一些与阴性名词相似形式的阳性名词，也有一些不分性别（在语境中被确认）的词。
The third declension is used for feminine nouns ending in ь.第三种变形用于以...结尾的阴性名词。
学习一门新语言时要把自己想象成重新建立一个新的人格
变格表格参考维基百科。
形容词
形容词一般置于所修饰的名词之前。
形容词分为三种：
Adjectives may be divided into three general groups:
qualitative (ка́чественные) – denotes a quality of the object; this is the only group that usually has degrees of comparison. 定性，这个情况下才有比较级。
relational (относи́тельные) – denote some sort of relationship; unlikely to act as a predicate or have a short form. 表关系
possessive (притяжа́тельные) – denote belonging to a specific subject; have some declensional peculiarities. 表所属
Russian differentiates between hard-stem and soft-stem adjectives, shown before and after a slash sign.俄语在斜杠的前后会展示 强词干和弱词干形容词。
形容词或副词的比较级。
有特殊情况，词形都发生了变化。一般情况下在形容词后面后缀即可，最高级可以添加前缀实现。
代词
代词分为人称代词，指示代词和疑问代词。与英语不同的是，俄语使用相同的形容从属词，和代词从属词。
数字
不定式，添加前缀或后缀来实现。
文法，俄语的语序可以乱放，但是有不同的含义，一般来说是SOV的顺序。
