Final answer:
To make a last name plural, typically add 's'. For names that end in 's', 'x', 'z', 'ch', or 'sh', you add 'es'. When indicating possession, add an apostrophe to the end of plural nouns that already end with 's', or apostrophe and 's' to plural nouns that do not end in 's'.
Step-by-step explanation:
To make a last name plural, you generally just add an 's' to the end of the name. For example, the singular 'Mr. Brady' becomes the plural 'the Bradys'. However, there are some specific rules to keep in mind regarding the use of apostrophes with plural forms. When pluralizing a last name that ends in 's', 'x', 'z', 'ch', or 'sh', you would typically add 'es'. For instance, the last name 'Jones' would become 'the Joneses'.
If the noun is plural and ends in an 's', you add just an apostrophe at the end to show possession. For example, 'the workers' benefits'. Conversely, if the noun is plural and does not end in 's', you add an apostrophe followed by an 's', as in 'the children's game'. Apostrophes are also used to form contractions, like 'can't' from 'cannot', or 'it's' from 'it is'. It's important to remember that apostrophes are not used to make regular nouns plural.
To pluralize the sentence 'People have their own opinions', you keep the subject 'people' and the possessive 'their' the same because they are both already in plural form. Thus, the plural sentence remains as 'People have their own opinions.' This inclusion considers everybody and excludes nobody from any gender identity.
