When it comes to describing a range of related products, there are several synonyms that can be used instead of the term "product family." For instance, the phrase "product line" is frequently used in marketing to refer to a group of items that share a similar theme or purpose, such as a line of skincare products or a line of kitchen gadgets. Similarly, the term "product range" may also be utilized to describe a collection of items that a company offers. Other potential synonyms for "product family" might include "product category," "product series," or "product group." Ultimately, the most effective synonym will depend on the specific context and audience.
