[Middle English cas, from Old French, from Latin cāsus, from past participle of cadere, to fall; see kad- in Indo-European roots.] |
A grammatical category indicating whether nouns and pronouns are functioning as the subject of a sentence (nominative case) or the object of a sentence (objective case), or are indicating possession (possessive case). He is in the nominative case, him is in the objective case, and his is in the possessive case. In a language such as English, nouns do not change their form in the nominative or objective case. Only pronouns do. Thus, ball stays the same in both “the ball is thrown,” where it is the subject, and in “Harry threw the ball,” where it is the object.
