The problem of case in Modern English nouns is one of the most vexed problems in English grammar. This can be seen from the fact that views on the subject differ widely. The most usual view is that English nouns have two cases: a common case (e. g. father) and a genitive (or possessive) case (e. g. father's). Side by side with this view there are a number of other views, which can be roughly classified into two main groups: (i) the number of cases in English is more than two, (2) there are no cases at all in English nouns. The first of these can again be subdivided into the views that the number of cases in English nouns is three, or four, or five, or even an indefinite quantity. Among those who hold that there are no cases in English nouns there is again a variety of opinions as to the relations between the forms father and father's, etc. Before embarking on a detailed study of the whole problem it is advisable to take a look at the essence of the notion of case. It is more than likely that part, at least, of the discussions and misunderstandings are due to a difference in the interpretation of case as a grammatical category. It seems therefore necessary to give as clear and unambiguous a definition of case as we can. Case is the category of a noun expressing relations between the thing denoted by the noun and other things, or properties, or actions, and manifested by some formal sign in the noun itself. This sign is almost always an inflection, 1 and it may also be a "zero" sign, i. e. the absence of any sign may be significant as distinguishing one particular case from another. It is obvious that the minimum number of cases in a given language system is two, since the existence of two correlated elements at least is needed to establish a category. (In a similar way, to establish the category of tense in verbs, at least two tenses are needed, to establish the category of mood two moods, etc.). Thus case is part of the morphological system of a language. Approaching the problem of case in English nouns from this angle, we will not recognise any cases expressed by non-morphological means. It will be therefore impossible to accept the theories of those who hold that case may also be expressed by prepositions (i. e. by the phrase "preposition + noun") or by word order. Such views have indeed been propounded by some scholars, mainly Germans. Thus, it is the view of Max Deutschbein 1 that Modern English nouns have four cases, viz. nominative, genitive, dative and accusative, of which the genitive can be expressed by the -'s-inflection and by the preposition of, the dative by the preposition to and also by word order, and the accusative is distinguished from the dative by word order alone. It should be recognised that once we admit prepositions, or word order, or indeed any non-morphological means of expressing case, the number of cases is bound to grow indefinitely. Thus, if we admit that of the pen is a genitive case, and to the pen a dative case, there would seem no reason to deny that with the pen is an instrumental case, in the pen a locative case, etc., etc. Thus the number of cases in Modern English nouns would become indefinitely large. This indeed is the conclusion Academician I. I. Meshchaninov arrived at.2 That view would mean abandoning all idea of morphology and confusing forms of a word with phenomena of a completely different kind. Thus, it seems obvious that the number of cases in Modern English nouns cannot be more than two (father and father's). The latter form, father's, might be allowed to retain its traditional name of genitive case, while the former (father) may be termed common case. 3 Of course it must be borne in mind that the possibility of forming the genitive is mainly limited to a certain class of English nouns, viz. those which denote living beings (my father's room, George's sister, the dog's head) and a few others, notably those denoting units of time (a week's absence, this year's elections), and also some substantivised adverbs (to-day's newspaper, yesterday's news, etc.). It should be noted, however, that this limitation does not appear to be too strict and there even seems to be some tendency at work to use the -'s-forms more extensively. Thus, we can come across such phrases as, a work's popularity, the engine's overhaul life, 1 which certainly are not stock phrases, like at his fingers' ends, or at the water's edge, but freely formed phrases, and they would seem to prove that it is not absolutely necessary for a noun to denote a living being in order to be capable of having an -'s-form. The more exact limits of this possibility have yet to be made out. The essential meaning of this case would seem to require an exact definition. The result of some recent investigations into the nature of the -'s form 2 shows that its meaning is that of possessivity in a wide sense of the term. Alongside of phrases like my father's room, the young man's friends, our master's arrival, etc., we also find such examples as nothing could console Mrs Birch for her daughter's loss, 3 where the implied meaning of course is, 'Mrs Birch lost her daughter'. The real relation between the notions expressed by the two nouns may thus depend on the lexical meaning of these nouns, whereas the form in -'s merely denotes the possessive relation. Up to now we have seen the form in -'s as a genitive case, and in so far we have stuck to the conception of a two-case system in Modern English nouns. There are, however, certain phenomena which give rise to doubts about the existence of such a system — doubts, that is, about the form in -'s being a case form at all. We will now consider some of these phenomena. In the first place, there are the expressions of the type Smith and Brown's office. This certainly means 'the office belonging to both Smith and Brown'. Not only Brown, whose name is immediately connected with the -'s, but also Smith, whose name stands somewhat apart from it, is included in the possessive relation. Thus we may say that the -'s refers, not to Brown alone, but to the whole group Smith and Brown. An example of a somewhat different kind may be seen in the expression the Chancellor of the Exchequer's speech, or the Oxford professor of poetry's lecture. These expressions certainly mean, respectively, 'the speech of the Chancellor of the Exchequer', and 'the lecture of the Oxford professor of poetry'. Thus, the -'s belongs to the groups the Chancellor of the Exchequer and the Oxford professor of poetry. The same of course applies to the groups the Duke of Edinburgh's speech, the King of England's residence, and many others. A further step away from the category of case is taken in the groups somebody else's child, nobody else's business, etc. Here the word immediately preceding the -'s is an adverb which could not by itself stand in the genitive case (there is an obvious difference between somebody else's child and, e. g., to-day's news, or yesterday's paper). The -'s belongs here to the group somebody else as a whole. It cannot, then, be an inflection making an integral part of a word: it is here part of a whole phrase, and, accordingly, a syntactical, not a morphological, element. Formations of this kind are by no means rare, especially in colloquial style. Thus, in the following sentence the -'s is joined on to a phrase consisting of a noun and a prepositional phrase serving as attribute to it: This girl in my class's mother took us [to the movies] (SALINGER), which of course is equivalent to the mother of this girl (who is) in my class. It is only the lexical meaning of the words, and in the first place the impossibility of the phrase my class's mother, that makes the syntactical connection clear. Compare also: . . .and constantly aimed to suggest a man of the world's outlook and sophistication. .. (The Pelican Guide to English Literature) The -'s is still farther away from its status as an inflection in such sentences as the following: The blonde I had been dancing with's name was Bernice something — Crabs or Krebs. (SALINGER); I never knew the woman who laced too tightly's name was Matheson. (FORSTER) This is the type usually illustrated by Sweet's famous example, the man I saw yesterday's son, 1 that is, the type "noun + attributive clause + -'s". Let us have a look at J. D. Salinger's sentence. It is obvious that the -'s belongs to the whole group, the blonde 1 had been dancing with (it is her name he is talking about). It need hardly be emphasised that the preposition with cannot, by itself, be in the genitive case. Such constructions may not be frequent but they do occur and they are perfectly intelligible, which means that they fit into the pattern of the language. All this seems to prove definitely that in the English language of to-day the -'s can no longer be described as a case inflection in nouns without, at least, many reservations. This subject has been variously treated and interpreted by a number of scholars, both in this country and elsewhere. The following views have been put forward: (1) when the -'s belongs to a noun it is still the genitive ending, and when it belongs to a phrase (including the phrase "noun + attributive clause") it tends to become a syntactical element, viz, a postposition; (2) since the -'s can belong to a phrase (as described above) it is no longer a case inflection even when it belongs to a single noun; (3) the -'s when belonging to a noun, no longer expresses a case, but a new grammatical category, viz. the category of "possession", for example, the possessive form father's exists in contradistinction to the non-possessive form father. An essential argument in favour of this view is, that both the form without -'s and the form with -'s can perform the same syntactic functions; for instance, they can both be subject of the sentence (cf. My father was a happy man and My father's was a happy life). It should be noted that the views listed under (2) and (3) lead to the conclusion that there are no cases in the Modern English noun. 1 Though the question is still under discussion, and a final agreement on it may have to wait some time, we must recognise that there is much to be said in favour of this view. We will, then, conclude the discussion by saying that apparently the original case system in the English nouns, which has undergone a systematic reduction ever since the earliest times in the history of the language, is at present extinct, and the only case ending to survive in the modern language has developed into an element of a different character — possibly a particle denoting possession. Different views have also been expressed concerning the scope of meaning of the -'s. Besides phrases implying possession in the strict sense of the term (my father's books, etc.), the -'s is also found in other contexts, such as my father's friends, my father's arrival, my father's willingness, etc. The question now arises how wide this scope may be. From this point of view it has been customary to point out that the relation expressed by the collocation "noun + + -'s + noun" is often a subjective relation, as in my father's arrival: my father's expresses the subject of the action, cf. my father arrives. This would then correspond to the so-called subjective genitive of inflected languages, such as Russian or Latin. It would, however, not do to say that the noun having the -'s could never indicate the object of the action: cf. the example Doughty's famous trial and execution,2 where the implied meaning of course is 'Doughty was tried and executed'. This would correspond to the so-called objective genitive of inflected languages. Now, though this particular use would seem to be far less frequent than the subjective, it is by no means impossible or anomalous. Thus it would not be correct to formulate the meaning of the -'s in a way that would exclude the possible objective applications of the -'s-formation.
