Object of investigation,to the levels of language hierarchy and to two plans of the language

 
Morphological typology 
studies the units of morphological level. It deals 
with two types of comparisons: 1) with morphological classification; 2) with 
grammatical categories. According to the morphological classification languages 
are classified due to their means of expression of the grammatical meaning. 
 
Grammatical categories may be of two types: primary grammatical 
categories, which deal with parts of speech; secondary grammatical categories 
deal with the categories within every part of speech separately: tense, aspect, 
voice, degrees of comparison, number, case , etc. Morphological typology is 
limited according to the number of languages applied to comparison. Topological 
operations, etalon languages are limited in this case correspondingly. 
Morphological typology studies morphological paradigms. It classifies languages 
into a) languages with highly developed morphology: Russian, Arabic; 
b) 
languages with less developed morphology: English, Bulgarian, Armenian, 
Persian; c) languages with non-developed morphology: Chinese. 
 
Syntactic typology 
studies the syntactic structure of different languages, 
which consists of two sublevels: phrase 
level 
and sentence level. Syntactic typology
studies types of syntactic relations and grammatical signals concerning the 
syntactic relations. In the system of languages there exist the following syntactic 
relations: 
coordination, 
subordination, 
predication. 
Syntactic 
ties 
are 
agreement,government and adjoining.Aggreement and government are productive 
in Russian,government and adjoining are productive in Uzbek, adjoining is 
productive in English,though all syntactic ties, agreement, government and 
adjoining, are found in the mentioned above languages.We speak about the 
productivity of the definite linguistic phenomenon in the language proceeding from 
its being uppermost in mind due to its usage much wider than the other ones used 
for the purpose taken into consideration
