Nervosa has no real definition in the English language. In Latin, it means "nervous".

For contextual purposes, it means "the psychological addiction to a behavior, belief, or habit" that effects the body via the nervous system, or the mind.

It is also a word commonly used in reference to botany. Nervosa, when used in botany, describes a trunk or tree like pattern of veins within the leaves.
