Anyway, my feeling is that language does evolve, but jargon endures. I love learning the proper jargon that accompanies a new area of specialization. I love tradition as well, and I've built a few traditional wooden boats. Boatbuilders use antiquated terms that are hundreds of years old. I can't even imagine the looks I'd get from fellow boatbuilders if I started talking about the "back of the boat" instead of calling it the "stern". There's port, starboard, fore, aft, bow, stern, sheer, breasthook, gunwales, keel, strakes, garboard, staving, transom, rocker, trunnel, stopwater, stem, thwart, spar, stealer, spiling, fid, chine, knee, carvel, buttock, bearding line, riband, scantlings, rake, lofting, deck, bilge, and so on.
There are dozens of boat-specific terms that could easily be replaced by ones more understandable to the uninitiated. But why? It would suck the soul right out of boatbuilding for me. Let the newbies learn the proper traditional terminology, or be shunned by those in the know. Any boatbuilder worth his salt would consider deliberately replacing these ancient and cherished terms with modern equivalents to be disrespectful to say the least. Can't we keep just a few traditional terms alive in billiards as well?
