particular, the variability of their status is expressed in the fact that 
some of them can be used in an isolated response position (for in-
stance, words of affirmation and negation, interrogative words, 
demonstrative words, etc.), while others cannot (such as preposi-
tions or conjunctions). 
The nature of the element of any system is revealed in the character 
of its function. The function of words is realised in their nomina-
tive correlation with one another. On the basis of this correlation a 
number of functional words are distinguished by the "negative de-
limitation" (i.e. delimitation as a residue after the identification of 
the co-positional textual elements),* e.g.-. the/people; to/speak; 
by/way/of. 
The "negative delimitation'' immediately connects these functional 
words with the directly nominative, notional words in the system. 
Thus, the correlation in question (which is to be implied by the 
conventional term "nominative function") unites functional words 
with notional words, or "half-words" (word-morphemes) with "full 
words". On the other hand, nominative correlation reduces the 
morpheme as a type of segmental signeme to the role of an element 
in the composition of the word. 
As we see, if the elementary character (indivisibility) of the mor-
pheme (as a significative unit) is established in the structure of 
words, the elementary character of the word (as a nominative unit) 
is realised in the system of lexicon. 
Summing up what has been said in this paragraph, we may point 
out some of the properties of the morpheme and the word which 
are fundamental from the point of view of their systemic status and 
therefore require detailed investigations and descriptions. 
the morpheme is a meaningful segmental component of the word; 
the morpheme is formed by phonemes; as a meaningful component 
of the word it is elementary (i.e. indivisible into smaller segments 
as regards its significative function). 
The word is a nominative unit of language; it is formed by mor-
phemes; it enters the lexicon of language as its elementary compo-
nent (i.e. a component indivisible into smaller segments as regards 
its nominative function); together with
