In one of his letters to Varro, Cicero says:
“Si hortum in bibliotheca habes, deerit nihil.”
I’ve found this translated as:
“If you have a garden and a library, you have everything you need” (wikiquote)
My understanding is that “in” can be translated as one of several prepositions (in, at, into, etc.); however, here it’s being translated as a conjunction. Is this correct? And are there any other examples of this?
