Homonym: Colon (Punctuation)
The colon is a punctuation mark that resembles two vertically aligned dots (:). It is used to introduce a list, a quote, or an explanation that follows. For example, you might say, "You will need the following items: a pen, paper, and a ruler." The colon signals to the reader that more information is coming.
In addition to its use in writing, the colon is also an important part of the human digestive system. It is the final section of the large intestine and plays a crucial role in absorbing water and electrolytes from indigestible food matter. The colon helps form and store feces before they are expelled from the body.
