The Classification of Words in Post-Structural Traditional Grammar In modern linguistics, parts of speech are discriminated according to three
criteria:
semantic ,
formal and
functional . This approach may be defined as
complex . The
semantic criterion presupposes the grammatical meaning of the
whole class of words (general grammatical meaning). The
formal criterion reveals
paradigmatic properties: relevant grammatical categories, the form of the words,
their specific inflectional and derivational features. The
functional criterion
concerns the syntactic function of words in the sentence and their combinability.
Thus, when characterizing any part of speech we are to describe: a) its semantics;
b) its morphological features; c) its syntactic peculiarities.
The lexemes of a part of speech are united by their meaning. This meaning
is a category-forming one. Therefore, it is referred to as categorical meaning.
Lexemes that have the meaning of substance or thingness are nouns, those having
the meaning of property are adjectives; those having the meaning of process are
verbs; those having the meaning of circumstantial property are adverbs. As
categorical meaning is derived from lexemes, it is often called lexico-grammatical
meaning. In the surface, lexico-grammatical meaning finds outward expression.
For instance, the meaning of substance, or thingness, is realized by the following
lexico-grammatical morphemes:-er,-ist,-ness,-ship,- ment. It is also realized by
specific grammatical forms constituting the grammatical categories of number and
case. These outward features are a formal criterion of classification. The functional
criterion concerns the syntactic role of a word in the sentence.
In accordance with the said criteria, we can classify the words of the English
language into
