Nouns. Tip #7: Possessive Nouns
Possessive nouns are nouns which possess something; i.e., they have something. You can identify a possessive noun by the apostrophe; most nouns show the possessive with an apostrophe and an s.
Example: The cat’s toy was missing.- Пропала кошачья игрушка.
The cat possesses the toy, and we denote this by use of ‑’s at the end of cat.
When a singular noun ends in the letter s or z, the same format often applies. This is a matter of style, however, and some style guides suggest leaving off the extra s.
Example: I have been invited to the boss’s house for dinner.- Меня пригласили в дом босса на ужин.
Example: Mrs. Sanchez’s coat is still hanging on the back of her chair.- Пальто миссис Санчес все еще висит на спинке стула.
Plural nouns ending in s take only an apostrophe to form a possessive.
Example: My nieces’ prom dresses were exquisite.- Выпускные платья моих племянниц были восхитительны.
