1.3.3 Grammatical categories
The structural frameworks provided by grammatical categories include abstract
distinctions which are made by means of word classes, number (singular and
plural), tense, etc. Here we will only look at the grammatical category of word
classes. Each word class is a category in itself. Depending on definitions used for
each word class, English can be said to have eight or ten different word classes,
as shown in the following list:
(17) Word classes
a. noun mother, bird, pleasure
b. pronoun I, you, she, someone, which
c. determiner the, a, this, two
d. verb say, cry, consider
e. adjective big, rich, happy
f. adverb happily, merely, very
g. preposition at, on, during, amongst
h. particle (hang) up, (hand) in
i. conjunction and, because, after, before
j. interjection alas!, oops!, wow!
Most of the word classes were first introduced and defined by Greek and
Roman grammarians. They gave them the name partes orationis, which was
literally translated into English as parts of speech and also gave rise to the verb to
parse ‘to analyze a sentence into its parts’. The grammatical category of word
classes is still used today, but the notional definitions given to them by tradi-
tional grammars are often at odds with linguistic evidence. Even modern
dictionaries still rely on traditional definitions and would define a noun as “a
word or group of words that refers to a person, place or thing”, a pronoun as
“one of a class of words that serves to replace a noun or noun phrase”, etc.
(Collins Dictionary). It is easy to find counterexamples which disprove these
definitions: For example, in the sentence Someone has stolen my wallet, the
pronouns someone and my cannot be said to “replace” a noun or a noun phrase.
Traditional definitions of word classes were based on the erroneous assump-
tion that the word classes are clearly definable in the first place and that all the
words of a language can be neatly grouped into one of them. In the same way that
prototypical and peripheral types of chairs are subsumed under the lexical category
“chair”, different types of words are subsumed under a grammatical category.
