ABSTRACT
The singular nominative case is the dictionary form of all declinable parts of speech: nouns, pronouns, adjectives and numerals. The nominative case is not governed by any prepositions. The nominative case can have singular and plural numbers. The nominative case has several roles in a sentence. It can indicate the core elements of the sentence, i.e. the subject or the predicate. The nominative case can also be used as part of some idioms, when making lists, giving names or addressing a person directly. The main grammatical role of the nominative case is to indicate the subject of the sentence. An impersonal sentence has no grammatical subject in the nominative case. In the past tense, the noun that forms the essential part of the predicate can be used either in the nominative case or instrumental case to convey two different ideas. In a sentence, the nominative case can have roles other than indicating the subject or predicate of a sentence.
