structure. Stability of this structure is proved by two factors: 1) absence
of the devision of nouns into classes, nouns were divided into classes in
Indo-European languages and this caused some synthetic languages to
be
inclined to be analytic; 2) presence of the stable word order , that is
attribute is placed before the word it modifies.
In Indo-European languages there was a three morpheme structure:
root+ stem forming suffix, which makes up a stem together with the
root and the third morpheme is case inflection. Stem-forming suffixes
were different, therefore stems of the nouns were different too.
In the result of the development of the language structure stem-
forming suffixes have lost their semantic
meaning and have become
phonetic component of words, interacting with case morphemes and
combined with the latter all together. Such phenomenon on the one
hand caused words' three-morpheme structure to change into a two-
morpheme structure; on the other hand it caused the formation of the
homonymical
case forms, which exist in old Germanic languages.
Further development of this process led to the disappearance of some
case forms ( or to the disappearance of case system) and to the change
of synthetic languages into analytic as it took place in the English
language which is synthetic inclined to be analytical and in some other
Germanic languages. As we have seen in the course of historical
development the structure of some inflected languages has changed
greatly. But there were not such changes in the structure of
agglutinative languages. In these languages case morphemes are
agglutinated
to unchangeable root stems, therefore case variants
couldn't come into existence, the latter has shattered the Indo-European
case system. Morphological limit, that is the place of agglutinating case
morphemes with root morphemes in Turkic languages remained
unchangeable for centuries. It is one of the reasons of the stability of
the agglutinative structure. The stable order of the word combination
“attribute and the word it modifies”should be understood in the broad
sense. In agglutinated languages attribute can be expressed by a word ,
by an adjective, by a noun, by a participle, by an attributive construction
and by an extensive member of the sentence:
