I'm trying to learn how to break apart sentences and understand each part's name and what exactly it does (excuse my ignorance; I've read quite a bit, but I'm still new at it). I came across the following construction and, simple as it seems, I can't figure out what it's called. I thought it might be considered an absolute phrase, but those are usually defined as having a participle. So what would the second half of these sentences be considered and what is their function? Am I way off base? Are these even grammatical? Thanks!
