Note 32 — Chapter II

The changes expressive of Relation are made on nouns in two ways: 1. On the beginning of the noun; 2. On its termination. The relations denoted by changes on the termination are different from those denoted by changes on the beginning; they have no necessary connection together; the one may take place in absence of the other. It seems proper, therefore, to class the changes on the termination by themselves in one division, and give it a name, and to class the changes on the beginning also by themselves in another division, and give it a different name. As the changes on the termination denote, in general, the same relations which are denoted by the Greek and Latin cases, that seems a sufficient reason for adopting the term case into the Gaelic Grammar, and applying it, as in the Greek and Latin, to signify "the changes made on the termination of nouns or adjectives to mark relation".[32] According to this description of them, there are four cases in Gaelic. These may be named, like the corresponding cases in Latin, the Nominative, the Genitive, the Dative, and the Vocative.[33] The Nominative is used when any person or thing is mentioned as the subject of a proposition or question, or as the object of an action or affection. The Genitive corresponds to an English noun preceded by of. The Dative is used only after a preposition. The Vocative is employed when a person or thing is addressed.
