The word "commentatorial" can be tricky to work with in writing. It refers to anything related to commentary or commentary style, but it lacks the versatility of synonyms which can be a better fit in certain contexts. Some other options might be "opinionated," "analytical," or "interpretive." These words give a similar sense of the expression of ideas or thoughts but are more nuanced and evoke subtly different ideas. "Opinionated" can imply a more forceful or dogmatic tone, while "analytical" suggests a more objective or rational approach. "Interpretive" carries more of a sense of understanding and translating complex subjects or ideas. With these synonyms, writers can convey their intended meaning more precisely and create more engaging content.
