--description--

You've already learned about demonstrative pronouns like this, that, these and those. Remember to use them to refer to specific things or people, considering their proximity in time or space.

The genitive case, often indicated by an apostrophe and s (like function's), is used to show possession or belonging, typically for people or objects. It tells people that something belongs to or is a part of something else.

The word purpose refers to the reason why something is done or used, or why something exists. For example, The purpose of a clock is to tell time.
