3. It is connected with Morphology because the word‘s content plane is a
unity of lexical and grammatical meanings.
4. The word functions as part of the sentence and performs a certain
syntactical function that is why it is also connected with Syntax.
5. The word functions in different situations and spheres of life therefore it
is connected with Stylistics, Socio- and Psycholinguistics.
But there is also a great difference between lexicology and other linguistc
disciplines. Grammatical and phonological systems are relatively stable. Therefore
they are mostly studied within the framework of intralinguistics.
Lexical system is never stable. It is directly connected with extralinguistic
systems. It is constantly growing and decaying. It is immediately reacts to changes
in social life, e.g. the intense development of science and technology in the 20
th
century gave birth to such words as computer, sputnik, spaceship. Therefore
lexicology is a sociolinguistic discipline. It studies each particular word, both its
intra- and extralingiustic relations.
Lexicology is subdivided into a number of autonomous but interdependent
disciplines:
1. Lexicological Phonetics. It studies the expression plane of lexical units in
isolation and in the flow of speech.
2. Semasiology. It deals with the meaning of words and other linguistic
units: morphemes, word-formation types, morphological word classes and
morphological categories.
3. Onomasiology or Nomination Theory. It deals with the process of
nomination: what name this or that object has and why.
4. Etymology. It studies the origin, the original meaning and form of words.
5. Praseology. It deals with phraseological units.
6. Lexicography. It is a practical science. It describes the vocabulary and
each lexical unit in the form of dictionaries.
7. Lexical Morphology. It deals with the morphological stricture of the word.
