Youʻre right, now knowing the correct terms of things isnʻt important, like volcanism. Now knowing why itʻs called volcanism isnʻt important either. My point is, regardless of the MEANING behind something isnʻt the important thing, itʻs having correct terminology. So I wouldnʻt call it "Exploding-Lava-ism" or "conical-molten-rock-ism". But by being corrected by someone who is educated on the correct terminology behind the concept of "Volcanology", I would be appreciative, not dismissive. And I wouldnʻt be going forth into the world sharing inaccurate information. Accurate information stems from an input of information, educators, peers, etc. However, if that information isnʻt accurate from the start, then the propagation on inaccuracies take hold.
