Definition
An 'annotation' is a note of explanation or comment added to a text, diagram, or other piece of information. Think of it like leaving a little trail of breadcrumbs to help yourself or others understand something better. Annotations can clarify, provide context, or offer critical perspectives. They are akin to sticky notes on a textbook, highlighting important points. Annotations are not usually a part of the main content, but rather additions to it. They serve to enrich or question the original material.
