recommend

Recommend is a verb meaning to present something as suitable or desirable and worthy of acceptance; to advise or counsel a course of action; or to endorse publicly. It can apply to objects, ideas, or people, such as recommending a book, recommending a policy, or recommending someone for a position.

Etymology and usage notes: The word derives from Old French recommander, from Latin commendare, meaning to entrust or commend. In modern English, "recommend" often takes a direct object ("I recommend this book") or a that-clause ("I recommend that you try the fish"). The phrase "recommend to" can be used for suggesting applicability to a person or group ("I recommend this course to beginners").

Relationships with related terms: "recommend" is related to "recommendation" (the act of recommending) and "endorse" (a public declaration of support). Unlike "advise," which emphasizes guidance, "recommend" implies a degree of approval or trust in the suggested option.

Computing context: In information retrieval and e-commerce, recommendation systems (recommenders) analyze user data to propose items you may like. Algorithms include collaborative filtering, content-based filtering, and hybrids. These systems aim to personalize options while balancing relevance, diversity, and user privacy.
