pair

A pair is like having two socks that match perfectly. You know how when you put on your socks, you have one for your left foot and one for your right foot? They look the same and work together to keep your feet warm. That’s what a pair is – two things that belong together and are usually the same or very similar.
Think about a pair of shoes. You wouldn’t want to wear just one shoe, right? You need both to walk properly. Each shoe is important, and together they make a pair. A pair is like a team, where both parts are needed to do the job right.
Imagine holding a pair of scissors. Scissors have two blades that come together to cut paper. If you only had one blade, it wouldn’t work as well. Both blades need to work together to make the scissors useful. This is another example of a pair, where each part has a special job, and together they do something amazing.
