neurotic

The word 'neurotic' is a modern medical term built directly from classical Greek components. Its core, 'neur-', traces back to the Greek 'neuron', which originally referred to a sinew or tendon before its meaning specialized to denote the nerve cord. The adjectival suffix '-otic' derives from the Greek '-ōtikos', used to form adjectives meaning "pertaining to" or "affected by". The term entered English in the 18th century via the medical Latin 'neuroticus', initially describing nervous diseases in a purely physiological sense. Over time, particularly with the rise of psychoanalysis, its meaning evolved from a literal disorder of the nerves to describe psychological conditions characterized by anxiety and obsessive behavior, reflecting a shift from a physical to a mental understanding of the "nerve" root's influence.
