Only too true! However, back to semantics, whether people study it or not, in the real world one has to accept that language is not always used correctly, and act accordingly. BAS could, for example, perfectly correctly answer 'yes' to a question here which asked "Can I install six new sockets on an unfused spur off a ring final circuit?". However, to answer 'yes', without any qualification, would clearly be plain irresponsibleSome have already abandoned the meaning of study.
