When it comes to describing something that has been simplified or reduced to its most basic elements, there are a variety of synonyms for the term "stripped down." Some possible options include things like "bare-bones," "minimalist," "basic," "skeletal," "unadorned," "plain," "straightforward," "undecorated," "spartan," and "unembellished." Each of these options emphasizes the idea of simplification or reduction, and can be used to describe a wide range of items or concepts, from a piece of machinery that has been simplified to its most essential components, to a piece of writing that has been stripped of any unnecessary words or phrases.
