particular
When you think about ‘particular’, picture a big box full of crayons. There are lots of crayons inside, but you want the red one. The ‘red’ crayon is particular because it’s the special one you need out of all the crayons. It’s like choosing your favorite teddy bear out of a big pile of toys. That teddy bear is particular because it’s the one you love the most.
Now imagine you are at a party with lots of balloons. Each balloon is a different color. If someone asks for the blue balloon, they want a particular balloon, not just any balloon. It’s like when you have a favorite snack, like cookies, and you only want the chocolate chip ones. The chocolate chip cookies are particular because they’re the ones you like best.
Think about a garden full of flowers. If you want to pick a yellow flower, that yellow flower is particular because it’s the one you chose from all the others. It’s like when you have lots of clothes, but you want to wear your striped shirt today. That shirt is particular because it’s the one you picked out of your whole closet.
