The correct pronunciation of “aesthetic” is “es-thet-ik”. The word is often mispronounced as “uh-sthe-tik”.
The word “aesthetic” comes from the Greek word “aisthetikos”, which means “pertaining to perception”. The word was first used in English in the 18th century to describe a branch of philosophy that dealt with the nature of beauty and art. Today, the word “aesthetic” is used to describe anything that is pleasing to the senses, especially in terms of beauty.
