I think I have met my grammatical match!
This is the killer paragraph:
“It turns out that …“Put up with” is what’s called a “phrasal verb” — a verb phrase that includes more than one word and in which the auxiliary word is very often a preposition acting as an “adverbial particle.” In other words, although structurally, the words “up” and “with” here are prepositions, functionally they’re adverbs modifying the verb “put” and thus don’t really need to follow the old rule …”
Awesome. ‘Night all.
