Bird?$-Rye View of Teutonic Grammar 267 four case-forms in the singular and four in the plural., making eight altogether, an$ the rules for using them were the same as the rules for the corresponding pronouns (p. 262) The nouns chosen as museum exhibits illustrate sound-changes described in the preceding chapter. The change from daeg to day is an example of the softening of the Old English gy and timge-Zunge, waeter-Wasser illustrate the shift from T to Z (initial) or SS (medial) Our table of Old English nouns with their modern German equiva- lents discloses two difficulties with which our Norman conquerors would have had to deal as best they could, if they bad condescended to learn the language of the people To use a noun correctly they would have had to choose the appropriate case-ending, and there was no simple rule to guide the choice There were several classes (declensions) of noun-behaviour. If the learner had followed the practice of modern school-books, he (or she) would have to know which declension a noun belonged to before he could decide what ending, singular or plural, the direct object, the indirect object, the possessive, or the form appro- priate to the preceding preposition ought to take. During the two centuries after the Conq jest these difficulties solved themselves. The distinction between nominative, accusative and dative forms was not essential, because it either depends on a quite arbitrary custom of using one or other case-form after a particular preposition, or does something which can be expressed just as well by word-order (pp 118 and 155) It had disappeared before the beginning of the four- teenth century The distinction between the singular and the plural, and the possessive use of the genitive case-forms do have a function, and a plural flexion together with a genitive have persisted Tor reasons we do not know the English people made the best of a bad job by the chivalrous device of adopting the typical masculine nominative and accusative plural ending -as (our -es or -s) to signify plurality Similarly the typical masculine or neuter genitive singular ~es (our 's or ') spread to nouns which originally did not have this genitive ending Perhaps, as Bradley suggests, the growing popularity of the -5 terminal was the survival of the fittest. It gained ground because it was easiest to distinguish The result was an immense simplification The words waeter> tunge, and bera were once representative of large classes of nouns, and there were others with plural endings in -a, -«» and -e To-day there are scarcely a dozen English nouns in daily use outside the class of those which tack on -5 in the plural Such levelling also occurred in Swedish, Danish and Dutch, but standardization of
