The word "vagarious" does not have an established etymology as it is not found in most English dictionaries. The term "vagarious" seems to be derived from the noun "vagary", which refers to an extravagant or unpredictable change in behavior, opinion, or action. "Vagary" itself comes from the Latin word "vagari", meaning "to wander" or "to stray". Adding the suffix "-ous" to "vagary" creates the adjective "vagarious", suggesting something characterized by vagaries or changeable behavior. However, the phrase "more vagarious" seems to be an adverbial form rather than a commonly used expression.
