Dear Patrick, (01)
You just made, very effectively, my point about language use. When I
see the word "entity" I do not take it to mean "word". If we want to
say "word" we should say "word". Nobody disputes that words and
semantics are malleable, as you indicate below. The word "entity" has
a respectable heritage dating long before its being co-opted (as has
been the word "ontology") by the IT community. (02)
