Definition: Anxiety is a feeling of worry, nervousness, or unease about something with an uncertain outcome. It is a natural human response to perceived threats and can range from mild uneasiness to intense fear. However, when anxiety becomes excessive, pervasive, and interferes with daily living, it may be classified as an anxiety disorder, which requires professional assessment and treatment.
Etymology and Origin: The etymology of “anxiety” traces back to the Latin word “anxietas,” from “anxius” (anxious, distressed), which is akin to the Ancient Greek “ἄγχω” (ánkhō, “to choke”). This shows a connection between the concept of anxiety and a sense of constriction or distress, evolving from ancient languages to its current usage.
