It's interesting to note how the meaning shifted:
* "Ludere" originally meant "to play" in the sense of "to engage in an activity for enjoyment".
* Over time, the word developed a more specific meaning related to "deceiving" or "tricking".
* This ultimately led to the modern English word "illusion", which refers to a false perception or a misleading appearance.
So, while "illusion" doesn't directly come from "play", it's derived from a word that originally had a playful connotation. This connection suggests the idea that an illusion is something that plays tricks on our senses or minds.
