nervosa

In English, "nervosa" is mainly seen as part of medical names such as anorexia nervosa and bulimia nervosa. In those phrases, it points to a condition linked to the mind or nervous system rather than to a simple physical cause. It is not a normal everyday word for feeling worried, and people do not usually use it alone in a sentence. Its main role is clinical and descriptive, giving a disorder name a formal, medical tone.

"Nervosa" comes from a form meaning "nervous," and in English it is mostly used inside medical terms rather than as a free-standing word. You are most likely to meet it in names such as anorexia nervosa or bulimia nervosa. In that setting, it suggests that the condition has a mental or nervous aspect. The word gives the name a formal, clinical feel.

That said, this is not a standard English adjective for daily speech. A person would say "nervous" or "anxious," not "I feel nervosa." It is also uncommon in plain literary description on its own. Because of that, a vocabulary card should treat it as a specialized medical element, not as a common label for a person's mood or personality.

So the safest way to understand it is this: when you see "nervosa," think of a clinical naming pattern, usually in eating-disorder terms, where it signals a nervous or mental component. It sounds formal and technical, and outside those set phrases, it is rare in modern English.
