just so we’re clear

The true meaning of a word is the meaning of the word—all connotations and denotations, i.e the things that are suggested or pointed to in the real or imagined world. The etymological composition of a word does not determine or rewrite meaning. Use creates and determines meaning, since using a so-called “true” or etymological meaning will inevitably yield a FAIL in conversations with speakers of a natural language. A helicopter is a flying vehicle, not a spiral-wing (“helico-pter”).
