Here's the breakdown:
* "Parler" means "to speak" in French, and it originates from the Latin verb "parlare," also meaning "to speak."
* "Parliament" comes from the Old French word "parlement," which means "speech, talk, discussion." This, in turn, is derived from the Latin verb "parlare."
Therefore, while not directly derived from "parler," the word "parliament" shares the same Latin root and ultimately reflects the concept of speech and discussion, which is fundamental to the function of a parliament.
