Origin:
late 18th century (in the sense ‘relating to perception by the senses’): from Greek aisthētikos, from aisthēta ‘perceptible things’, from aisthesthai ‘perceive’. The sense ‘concerned with beauty’ was coined in German in the mid 18th century and adopted into English in the early 19th century, but its use was controversial until much later in the century.
