Definition: The word "achymous" has a long etymology, but it's generally considered to have originated from the Ancient Greek "aechus", meaning "sun". The term was first used in Roman mythology as an expression for a deity who controls the sun. In English usage, "achymous" is used to refer to someone or something that is not very visible and therefore cannot be seen by others. It's often used to describe something that is hidden away from view or not easily seen. For example, a "hidden treasure" could be described as "achymous". Some people might argue that the etymology of "achymous" is less clear than other words, such as "acquaintance". While it may have roots in Latin, there's no evidence to suggest that the word was originally a word in Greek or Roman usage. However, the term has become synonymous with the concept of an unknown person or object being invisible to others. Overall, "achymous" is a versatile and often used adjective that can mean something that is not easily seen or known by others.
