It ought to be emphasised that what we mean here is the grammatical category of number, and the question is, in what pronouns and to what extent that category is actually found. , It will be easily seen that the category of number has only a very restricted field in pronouns. It is found in the pronouns this/ these, that / those, other / others (if not used before a noun). We need not dwell here on the very peculiar means which are used to form the plural of this and of that. The question is one of the history of English, rather than of Modern English structure. We can limit ourselves to the statement that the method by which each of the two words forms its plural is quite individual and unanalysable from the viewpoint of the modern language. As to the pronouns I / we; he, she, it / they, it must be stated that there is no grammatical category of number here. We is not a form of the pronoun I, but a separate word in its own right. In a similar way, they is not a form of he, or she, or it, or of all of them, but a separate word. There is no grammatical category of number either in the pronouns my / our; his, her, its / their, and mine / ours; his, hers / theirs. E. g., her and their are different words, not different forms of one word. A peculiar difficulty arises here with reference to the pronouns myself / (ourself), ourselves; yourself / yourselves; himself, herself, itself / themselves. If we compare the two pronouns myself and ourselves, we shall see at once that the difference between the first elements of the two words is purely lexical (just as in the corresponding words my and our), whereas the second elements differ from each other by the same suffix -s that is used to form the plural of most nouns. 1 Thus we are brought to the conclusion that ourselves is essentially a different word from myself. There are no other grammatical categories in the English pronoun: there is no category of gender. The pronouns he, she, it, and also the pronouns his, her, Us; his, hers; himself, herself, itself, are all separate words. Thus, she is not a form of the word he but a separate word in its own right.
