The term "parts of speech" though firmly established, is not a very happy one. What is meant by a "part of speech" is a type of word differing from other types in some grammatical point or points.
The principles on which the classification is based are three in number, viz. (1) meaning, (2) form, (3) function. Each of these requires some additional explanations.
(1) By meaning we do not mean the individual meaning of each separate word (its lexical meaning) but the meaning common to all the words of the given class and constituting its. essence. Thus, the meaning of the substantive (noun) is "thingness". This applies equally to all and every noun and constitutes the structural meaning of the noun as a type of word. Similarly, the meaning of the verb as a type of word is that of "process", whatever the individual meaning of a separate verb may happen to be. We shall have to dwell on this later in considering every part of speech in detail.
(2) By form we mean the morphological characteristics of a type of word. Thus, the noun is characterised by the category of number (singular and plural), the verb by tense, mood, etc. Several types of words (prepositions, conjunctions, and others) are characterised by invariability
By function we mean the syntactical properties of a typo of word. These are subdivided into two, viz. (a) its method of combining with other words, (b) its function in the sentence; (a) has to deal with phrases, (b) with sentence structure. Taking, as we did previously, the verb as a specimen, we can state that, for example, a verb combines with a following noun (write letters) and also with a following adverb (write quickly). As to (b), i. e. the syntactical function of a verb in a sentence, it is that of a predicate.1
