👉 Archness is a term in linguistics that describes the quality of something that appears to be very similar or identical to another, even though it has been constructed differently. It is often used to describe the appearance of something that seems like it could not possibly exist independently from another object. For example, if someone says "The archness of the moon is mesmerizing," they are implying that the moon's light and beauty seem to be very similar or identical to what we can see from a distance.
