Questions & Answers about Arx supra urbem stat.
Because supra takes the accusative case here. In Latin, some prepositions regularly govern a particular case, and supra is one of the prepositions that normally takes the accusative.
So:
- urbs = city (dictionary form, nominative)
- urbem = city in the accusative singular
In this sentence, supra urbem means above the city.
The sentence breaks down like this:
- Arx = subject, the citadel / fortress
- supra urbem = prepositional phrase, above the city
- stat = verb, stands
So the structure is:
Subject + prepositional phrase + verb
Latin word order is more flexible than English word order because the endings show what each word is doing.
Because arx is the subject of the sentence, so it is in the nominative case.
Here are two forms of the noun:
- arx = nominative singular, the citadel as subject
- arcem = accusative singular, the citadel as direct object
Since the citadel is the thing doing the standing, Latin uses arx.
