What is a synonym for 'annotate' that involves adding commentary to a text?

The term 'annotate' refers to the act of adding notes or comments to a text to provide explanations, insights, or additional information. 'Comment' is a direct synonym because it effectively conveys the idea of providing commentary or remarks about the content. When someone annotates a document, they are often leaving commentary that can help explain, critique, or enhance understanding of the material. This process enriches the reader's experience and comprehension.

Options like 'elaborate,' 'summarize,' and 'clarify' have different meanings. 'Elaborate' generally means to add more detail or expand upon a subject rather than simply commenting on it. 'Summarize' focuses on condensing information into a shorter form, capturing the main points without additional commentary. 'Clarify' involves making something clear or easier to understand, often by rephrasing or explaining it but not necessarily adding personal commentary. Therefore, 'comment' aligns perfectly with the essence of annotating, making it the correct choice.
