I learned the word "perspicacious" a while ago, but I think I might be using it incorrectly. Recently, I tried to use it in writing to say
He wrote a perspicacious report on . . .
But something about it sounded off. So I changed it to
He perspicaciously wrote a report on . . .
But that wasn't exactly what I wanted to say. I wanted to suggest that his report deeply and acutely penetrates the issue, not that his writing process was illuminating.
Was the first example actually an incorrect usage of the word? If not, why did it strike me as strange or wrong?
My best guess is that "perspicacious" is a word that can only apply to people, or at least to animate beings; hence, when I applied it to something inanimate, it sounded strange. Is that an accurate assumption? Or is there something else I'm misunderstanding about the word?
