The noun and its grammatical categories in the english and uzbek languages

-й
 for the nouns in masculine gender: 
край, сарай, ручей; 
-а, -я
 for the nouns in feminine gender: река, земля; 
-о, -е, 
-мя
 for the nouns in neuter gender: окно, море, знамя. 
In stated words singularity is expressed materially, that is by means of special 
morphemes. Now we'll see the words where singularity is expressed by zero 
morphemes: городO, домO, зверьO, дверьO, etc. 
 
In Russian singularity is expressed in case forms (нет)рек
и
, (нет) 
тетрад
и
,(нет) окн
а
, (нет)дом
а
. In stated examples singularity is expressed in 
case forms 
-и
and 
–a
. This way we find out that affixal morphemes 
-и
and -
a
 
(genitive case forms for feminine, masculine and neuter genders) express 
singularity. In word-forms городом-городами one can easily notice that the 
affixal morpheme 
-ом
expresses singularity, objectness, case, gender and the 
affixal morpheme -
ами
 expresses sems of plurality, objectness and case. 
In English singularity is expressed by a zero morpheme, for example: townO, 
playO, footO , etc. It is interesting to mark that in Uzbek as it is in English 
singularity of nouns is expressed by a zero morpheme. Further we'll use words 
marked for the presence of word form, non-marked for the absence of word-form. 
So we can see that the meaning of singularity of nouns in Russian can be marked 
and non-marked, in English and in Uzbek it is only non-marked. The category of 
plurality in these languages is marked.
