How do you change noun phrases to possessive form?

Answer 1

A noun phrase is a group of words based on a noun that function together as a noun in a sentence.

Examples:

My bicycle is new. (the noun phrase 'my bicycle' as the subject of the sentence)

I bought my bicycle at Sears. (the noun phrase 'my bicycle' as the direct object of the verb 'bought')

A possessive noun is formed by adding an apostrophe s ('s) to the end of a noun, or just an apostrophe (') the the end of a plural noun that already ends with an s.

Examples:

My bicycle's tire is flat. (the noun phrase 'my bicycle's tire' is the subject of the sentence)

I can fix my bicycle's tire myself. (the noun phrase 'my bicycle's tire' is the direct object of the verb 'can fix')

Answer 2

To change a noun phrase to possessive form, add an apostrophe and an "s" ('s) to the end of the noun. For example, "the cat's tail" or "Sarah's book." If the noun is plural and already ends in "s," just add an apostrophe after the "s" (s'). For example, "the girls' room" or "the dogs' leashes."
