The Dative case is chiefly used to indicate the person for whom (that is, for whose advantage or disadvantage) an action happens or a quality exists.

adding ‘s to the singular. Explanation: The genitive case in Modern English is used to indicate possession, that is to say to indicate that something belongs to someone. The genitive case is shown adding ‘s to a singular noun. However, the genitive case of plural nouns is formed only by adding an apostrophe (‘).

The genitive case (or function) of a noun or pronoun’s inflected form shows ownership, measurement, association, or source. Adjective: genitival. The suffix -‘s on nouns (such as pronoun above) is a marker of the genitive case in English. The genitive case can also be indicated by an of phrase after a noun.

The genitive case is predominantly used for showing possession. With nouns, it is usually created by adding ‘s to the word or by preceding it with “of.” Most people will encounter the term “genitive case” when studying a language other than English.

In grammar, the genitive case (abbreviated gen), is the grammatical case that marks a word, usually a noun, as modifying another word, also usually a noun—thus, indicating an attributive relationship of one noun to the other noun.

Using Apostrophes to Form Possessive Nouns

Here are the basic and very general rules for making a dative in singular:

• If a word ends in “-us”, then the dative ends in “-o”.
• If a word ends in “-a”, then the dative ends in “-ae”.
• If a word ends in “-o”, then the dative ends in “-oni”.
• If a word ends in “-ns”, then the dative ends in “-nti”.

The plural always ends in ‘-a’. Accusative singular for masculine and feminine nouns always ends in ‘-m’; accusative plural for masculine and feminine nouns always ends in ‘-s’. Genitive plural of all declensions ends in ‘-um’. Dative and ablative plurals are always the same.
