Cap

Cap is short for "capitalization." Just like how we use big and small letters to write words, we can use uppercase and lowercase letters to write words in a special way called "capitalization."

For example, the word "mom" has a lowercase "m" and a lowercase "o," but if we capitalize the first letter, it becomes "Mom" with a big "M."

Cap can also refer to a hat that covers our head. This hat is usually round and has a flat top. Some caps have a visor that sticks out in front to shade our eyes from the sun. Caps can be worn for fashion, sports, or even for safety, like a hard hat worn in construction sites.

So, to sum up, cap can mean capitalization or a type of hat that covers our head!
