My understanding is that not ending a sentence in a preposition is pretty much the only rule of word order in Latin. I don’t know why; I’m not a Latin speaker either.
As Senegoid pointed out, the rule on not splitting infinitives is easier to explain; it’s impossible to do in Latin because infinitives are a single word. In English, infinitives are two words but Latin-influenced scholars invented a rule that if it couldn’t be done in Latin, it shouldn’t be done in English.
When the boy’s father came into his room at bed time carrying a book about kangaroos, the little boy said “Daddy, why’d you bring that book I didn’t want to be read to from about Down Under up for?”
(And yes I realize “Down Under” is really a noun in that construction.)
Depending on their total hootworthiness. The two examples together could add up to one hoot, or they could each independently be an individual hoot, for a total of two hoots.
If one is easily amused, then I suppose each terminal preposition alone is worth a hoot. If I’ve counted aright, that gives us 8 hoots in those two examples.
If Johnny has 8 hoots and he gives a hoot, how many hoots does Johnny have left? Are hoots conserved?
