What does recommender mean?
A recommender is a person or system that suggests a choice to someone else. A person may act as an academic or professional recommender by endorsing a candidate, while a digital recommender uses information about a user's preferences, behaviour, or past selections to suggest books, films, music, products, and other content. The term is especially common in discussions of streaming services, online shops, search systems, and artificial intelligence. It is distinct from a recommendation: the recommender supplies or produces the suggestion, whereas the recommendation is the suggestion itself. In everyday conversation, people more often say that someone recommended a book or that an application recommended a video, but recommender is useful when naming the person or mechanism responsible for making such suggestions.
A person who recommends or formally endorses someone or something.
"Applicants were asked to name two academic recommenders."
Common in academic, professional, and reference contexts.
A software system or algorithmic tool that suggests items or content based on a user's preferences or behaviour.
"The website's recommender adapted its suggestions after each selection."
Common in technology, commerce, and media contexts.
The plural is used for multiple people or systems that provide recommendations.
"The platform compares ratings from recommenders across several categories."
A recommender can turn a massive catalogue into a personalised selection: the algorithm does the suggesting while the user receives the recommendation.

Where does recommender come from?
The word comes from the same root as recommend, a word that entered Middle English from Old French recommander. That French form drew on Latin recommendare, formed from re-, meaning 'again' or 'back', and commendare, meaning 'to praise' or 'entrust'. The sense developed from formally endorsing or praising someone to suggesting that a particular choice may suit another person's needs or tastes.
How recommender is actually used
In academic and professional contexts, the word often refers to someone who evaluates an applicant or candidate. In technology and commerce, it commonly denotes an algorithm or system that generates personalised suggestions. It is less common than the related noun recommendation in general speech.
