When trying to describe something but not being specific enough, the phrase "something of the kind" is often used. However, there are plenty of synonyms that can be utilized to convey the same message. For instance, "a similar thing" or "a comparable object" both serve as options that would express a similar meaning. Similarly, "a thing alike" or "a related item" might also suffice. "Something similar" or "something akin" would be fitting messages, as well. All of these phrases share the same concept of relativity, allowing you to be more precise without choosing one specific object or thing.
