Question

How would you make the word “geese” possessive? It’s geese’s right? Or is it geese’? Geese’s’?

Answer 1

Hint: Showing possession in English is a reasonably simple matter. We can manage to transform most singular nouns into their possessive form by adding an apostrophe and a s.

Complete answer:
The "geese" possessive form is "geese's". Since the term geese does not end with an s, it will not be geese '. It wouldn't be geese’s’, because that's wrong grammatically.

Possessive forms are also modifiers used as nouns, or gerunds, for verb forms. How we read the expression would be influenced by using the possessive. For example "I'm worried about Joe running in the park after dark" means I'm worried about Joe and the fact that after dark, he runs in the park (the word "running" is a present participle modifying Joe).

Modifiers used as nouns, or gerunds, for verb forms are also possessive forms. Using the possessive will impact how we interpret the word. For example, 'I'm worried about Joe running after dark in the park' means that I'm worried about Joe and the fact that he runs in the park after dark (the word "running" is a present participle modifying Joe).

You will need to add an apostrophe, followed by an s, to create the possessive form with nouns whose plurals are irregular. Examples:
She wants to open a clothing store for women.
Programming for kids is not a high priority.
The supply of food for the geese was in danger.

Already, most plural nouns end in s. Only add an apostrophe after the s: to establish their possessive one.
The big blue one on the corner is the Pepins' home.
The normal source of water for the lions’ has dried up.
The scents of the gases’ blended and were nauseating.
Hidden in the corner were the witches' brooms.
The babies’ beds were all in a row.

Note: With bits of furniture and buildings or inanimate objects in general, many writers consider it poor form to use apostrophe-s possessives. We should write "the edge of the desk" instead of "the desk's edge" (according to certain authorities), and instead of "the hotel's windows" we should write "the windows of the hotel."
