I usually just call these “free variables” by analogy to that term’s usage in mathematics/statistics, but “aether” seems good too since, if nothing else, when I say “free variable” to people who don’t know the jargon they just sort of roll over it whereas they’d have a much harder time doing that if I said “aether”.
