Sensory comes from Latin sensorius, from sensus ('feeling, perception'), the past participle of sentire ('to feel, perceive'). The historical chain includes Latin sensus and Latin sentire. Older glosses in the chain include "feeling, perception" and "to feel, perceive", which help explain the semantic range of the modern word. Morphologically, sensory is best read as borrowing, yielding an English adjective shaped by both form history and later usage. In current English it functions as an adjective, with the sense "relating to sensation or the physical senses". related forms include sense, sensation, sensitive, and sensorial. The result is an English adjective whose etymology preserves the older forms while supporting the word's specialized modern meaning.
