The tears were running visibly down his face.
Tears can BE visible, but can they RUN visibly? That is, is this an adjective (modifying tears) which is being forced into adverb (modifying run) position?
I know it's not a felicitous sentence overall, but let's just focus on "running visibly." We know what it means-- the guy isn't trying to hide his tears. But if the narrator sees the tears, why do we need "visibly"? Also, really, running visibly? I don't even know why that makes my skin crawl.
What do you all think? If you were editing, would you let that sentence go by?
