Quite so. As I have frequently demonstrated and reported, if one goes into a shop and asks for a lamp for one's table lamp/standard lamp/inspection lamp/headlamp/whatever, one will usually get some very funny looks - and if one asks to be directed to where one can find lamps, one is most unlikely to end up looking at light bulbs
Again, agreed. Maybe one of the worst examples (since the confusion was created by those who should know better) is the "Type B" RCD!
Indeed. I have no problem with industries/disciplines having their own terminology and jargon (those I am involved with do), but it is not realistic or appropriate to expect people who are not trained professionals in the industries/disciplines to be aware of that terminology/jargon.
