isolate

To isolate something means to keep it apart from others in a physical, emotional, or practical way. A scientist may isolate a virus in a lab to study it. A person may feel isolated after moving to a new city and not knowing anyone. You can also isolate a problem so you can see what is really causing it. Sometimes this kind of separation helps with safety, study, or focus. Other times it means being cut off and lonely.

The word "isolate" carries a strong sense of separation. At its core, it means to set something apart and keep it away from others. That separation can happen in several different ways.

In a physical sense, you might isolate a patient with a contagious disease to stop an infection from spreading. In science, researchers isolate a substance, cell, or virus so they can study it more clearly. A remote village can also be isolated because it is far away and hard to reach.

But the idea is not always physical. A person can feel isolated even in a crowd if they feel emotionally cut off and alone. Someone might isolate themselves by pulling away from friends, family, or social situations.

The word also has a problem-solving meaning. To isolate a variable in an experiment means to look at its effect without other factors getting in the way. More generally, if you isolate a cause, error, or detail, you separate it from everything else so you can understand it better.

Historically, "isolate" is linked to the Latin word "insula," meaning "island," which fits the image of something standing alone and apart.

So whether the setting is medical, emotional, or scientific, the word usually suggests separating someone or something from the rest. Sometimes that separation is useful and necessary. Sometimes it feels harsh or lonely.
