Rudi, none of this needs to boost anyone's blood pressure. I am just musing at how language evolves in funny directions. Some of it irritates me, but not most of it. I might have thought that as we evolve, we would be become more accurate over time, so it's funny that in some ways, we become less accurate, and to understand a word, we have to learn layers of history behind the word.

My observations of our uses of the word triangle are not irritations at all, just curiosities.

Bottom bracket is one that does irritate me, and it's my fault more than anyone's. Newcomers to cycling might find it confusing to hear us speaking of a bracket that isn't a bracket at all.
