Nouns are inflected for gender (masculine, feminine, neuter), number (singular and plural), and case: nominative, accusative, genitive, dative. Except in -u- stems, the vocative has the form of the accusative and/or is syncretized with the nominative. Demonstratives and pronominals have a residual instrumental, e.g. þe (by this), and ablative, e.g. jáinþro (from there). Adjectives are similarly inflected but also have strong and weak forms. Comparatives and nonpast participles are weak. The precise syntactic status of D-words (demonstratives, determiners, and articles) is impossible to test. Personal pronouns of the first and second person are inflected for singular, plural, and dual, and have no gender distinction. The third person pronoun has all three genders but only singular and plural number. Interrogative and indefinite pronouns are morphologically identical. Gothic has a rich negative polarity system. Numerals are partly inflected and partly indeclinable. Deictic adverbs belong to an old local case system.
