What does sentience mean?
Sentience is the capacity to experience the world consciously, including sensations, emotions, pleasure, and pain. In everyday use, the word often appears in debates about the ethical treatment of animals: whether a creature can feel suffering or comfort can affect how it should be handled. It is also important in philosophy and discussions of artificial intelligence, where the question is whether a system merely processes information or possesses subjective experience. The word is more specific than awareness, which can refer to attention or knowledge of one's surroundings, and more general than sentiment, which usually means a particular feeling or attitude. Sentience is therefore especially useful when the central concern is whether an experience has a felt, conscious quality from the perspective of the being experiencing it.

Where does sentience come from?
Sentience comes from the Latin noun sentientia, meaning “feeling” or “perception,” derived from sentire, “to feel” or “to perceive.” The adjective sentient and the related English words sensation, sentiment, and consent ultimately share this root. English adopted the noun in the early 19th century, when it was used especially in philosophical discussions of mind and moral perception.
