I've yet to come up with my definitive list of five words, but in the meantime, some preliminary thoughts.
First, I would rather not ban perfectly good words that simply have the misfortune to be (over)used in lazy or inaccurate ways. "Sheer" as an intensifier, for example, is a useful word that occasionally is the only word that will perfectly convey the intended meaning. No blanket bans there.
Nor should reasonable technical terminology suffer, so long as it can be presented in contexts where the gist if not the precise meaning is conveyed. Technical terms are not the same as jargon words: the former can be empowering when mastered and they usually can be attached to something that you can hear and/or see; the latter ultimately just exclude, especially when they are adopted for abstract and intangible concepts. Looking at the Whitney examples, it's important to note how few of them contained any actual technical terms referring to practical art techniques or visual effects – but they were full of conceptual jargon.
