Questions & Answers about Auriga equos incitat.
Because auriga is in the nominative case, which is the case normally used for the subject of the sentence.
In this sentence:
- auriga = the subject, the charioteer
- equos = the direct object, the horses
- incitat = drives/urges on
Latin often shows each word’s job by its ending, not mainly by word order.
The ending -os shows that equos is accusative plural.
That tells you two things:
- accusative = it is the direct object
- plural = it means horses, not horse
The noun is equus in the nominative singular, but when it becomes a plural direct object, it changes to equos.
A quick comparison:
- equus = horse
- equum = horse as a singular direct object
- equi = horses
- equos = horses as a plural direct object
That is a very common question. In Latin, nouns ending in are often , and many first-declension nouns are feminine. But not all of them are.
