Etymology

The word "commentary" originates from the Latin commentarius, meaning "notebook" or "memorandum," derived from commentari ("to meditate, note, or explain"). The root comment reflects the act of providing observations or annotations, while the suffix -ary (from Latin -arius) signifies something pertaining to or connected with the root. Over time, the term evolved to emphasize structured explanations, particularly in academic, media, or analytical contexts.
