To isolate something means to separate it from others or keep it apart.
When we talk about isolating something, we usually mean keeping it alone or away from other things. For example, if you're working on a project and need quiet time, you might try to isolate yourself in a library or a quiet room. This way, you can focus without distractions from people around you. You might also see scientists talking about isolating a new discovery or a rare plant, which means they're keeping it separate from other similar things so they can study it more closely.
Something that has been isolated.
