Questions & Answers about Post longam noctem spes nova oritur.
Because post is a preposition that takes the accusative when it means after. So nox becomes noctem after post.
In other words:
- post
- accusative
- nox = nominative singular, the basic dictionary form
- noctem = accusative singular
So post longam noctem means after a long night.
Because longam has to agree with noctem.
Latin adjectives must match the noun they describe in:
- gender
- number
- case
Here:
- noctem is feminine, singular, accusative
- so the adjective must also be feminine, singular, accusative
- therefore we get longam
So:
- longa nox = a long night as a subject
- longam noctem = a long night as the object of post
