1. Present several options of the same noun: "house", to "house", "house". How to define its initial form (or a dictionary form)? An initial form of a noun is the Nominative case form. This case designates the concept expressed by a word. Most often nouns in this case serve as a subject in the offer, is more rare - a predicate. The Nominative case answers questions: "who?", "that?" For example, "that?" – "house", "who?" – "bird". Ask similar questions to define a noun form.

3. Consider that some nouns have only plural form and to alter them, having led to the only thing, it is impossible. It is possible to carry to them, for example, names of time spans, pair objects, mass of substance: "day", "glasses", "trousers", "everyday life", "pasta", "vacation", "ink", "scissors". An initial form at similar nouns is plural Nominative case form.

For example: "Hours hang on a wall" (here the noun will have "hours" the initial form only in plural). Or: "In these hours the sky usually such light" (the initial form of a noun will have "hours" an appearance "hour").
