Usage
What does annotate mean? To annotate is to add notes or comments to a text or something similar to provide explanation or criticism about a particular part of it. Such notes or comments are called annotations. Annotation can also refer to the act of annotating. Annotations are often added to scholarly articles or to literary works that are being analyzed. But any text can be annotated. For example, a note that you scribble in the margin of your textbook is an annotation, as is an explanatory comment that you add to a list of tasks at work. Something that has had such notes added to it can be described with the adjective annotated, as in This is the annotated edition of the book. Example: I like to annotate the books I’m reading by writing my thoughts in the margins.

Etymology
Origin of annotate
First recorded in 1725–35; from Latin annotātus “marked down,” past participle of annotāre “to mark down,” from an- an- 2 + notāre “to mark” ( see note)
Explanation
When you annotate, you write critical explanations to add extra insight about something. These explanations can be necessary to understanding writings in which the language might be difficult to make sense of without clarification. The heart of the word annotate is the word note. The Latin annotātus means "noted down," making the word a breeze to remember. A writer will annotate parts that need extra explanation in technical works or classic writings in which the language or concepts might be difficult to grasp. In fact, some works, like James Joyce’s "Ulysses," have entire separate volumes of annotations, and readers must shift back and forth from the novel to the annotations. Now that's a dedicated reader!
