Definition of the word nervous

The word "nervous" has a fascinating history. It originates from the Latin word "nervus," meaning "sinew" or "string." In ancient Greek, the word "neuron" referred to the sinews or tendons that connect muscles to bones. Over time, the concept of nerve fibers, or "neura," was developed, suggesting a connection between the brain and the rest of the body through a network of fibers. In the 14th century, the word "nervous" emerged, initially referring to the "nerves" in the sense of physical sinews or fibers. By the 16th century, the term began to be used to describe emotions or mental states, such as agitation or anxiety, as if they were connected to the nervous system. Today, "nervous" connotes feelings of apprehension, unease, or anxiety, often in response to a particular situation or stimulus.
