Questions & Answers about Eques equum ducit.
Because eques is a singular noun, and its dictionary form happens to end in -es. In Latin, singular nouns do not always end in -us or -a.
Eques means horseman / rider / cavalryman and is a third-declension noun. Its nominative singular form is simply eques.
So:
- eques = the rider / a rider (subject form, singular)
Because equum is the accusative singular form, which marks the direct object of the verb.
In this sentence, the rider is doing the action, and the horse is receiving the action. So:
- eques = subject
- equum = direct object
The basic forms are:
- equus = horse (nominative singular, subject form)
- equum = horse (accusative singular, object form)
Latin changes noun endings to show their job in the sentence.
