Questions & Answers about In foro poculum ex argento videmus.
Because the preposition in takes the ablative when it means in or on in the sense of location.
- forum = forum, marketplace
- foro = in the forum / at the forum
So in foro means in the forum, not movement into it. If Latin wanted to emphasize motion into the forum, it would usually use in with the accusative instead.
Because it is the direct object of videmus.
In the sentence, we see what?
Answer: the cup.
That makes poculum the direct object, so it appears in the accusative singular.
A useful thing to notice is that poculum is a neuter noun, and in the singular its nominative and accusative forms are often the same. So here poculum could look like a subject form to an English speaker, but in this sentence it is functioning as the object.
The verb tells you. Videmus means we see.
The ending -mus shows first person plural, so the subject is . Latin often leaves the subject pronoun unstated because the verb ending already gives that information.
