The problem with spirit is that it sounds religiously related...it doesn't have to be but it sounds it, unless you''re talking about alcohol.
Its like how when Einstein and Hawking, Pantheists etc, use the word "God" in a metaphorical sense. I mean if you use the word "God" and spirit in a metaphorical sense, you CAN use it to describe anything. as Steven Weinberg said, and I paraphrase: "If you say God is energy, or God is the universe then you can find God in a lump of coal".
So the problem with these words is people will think there's something supernatural in them even when you're only using them metaphorically.
