Possessives

To indicate possession in English, you will use either the preposition of or the -"s form. The latter is used much more frequently in informal English.

--This is the office of the attorney.
-->This is the attorney"s office.

--Here is the desk of Mr. Young.
-->Here is Mr. Young"s desk.

--I know the family of Mrs. Jones.
-->I know Mrs. Jones"s family.

Note the change in word order when the -"s form is used. The owner is listed first, followed by the thing owned.
