... that is, words that are originally a preposition followed by a noun, but came to be written as one word.
How are those words accented? Do they behave entirely as single words so that invicem would be IN-vi-cem, or do they remain accented as two words so that invicem would be the same as in vicem and so in-VI-cem? Or is in vicem accented as one word in any case (whether it's written as one or two) because the preposition is enclitic so that the prepositional phrase functions as one word? Or does it vary? Or do we even know?
