"The boys see a powerful horse."

Translation: Taobi kostōbe annī urnesi.

[BuffyMarq]

Whats with the accents on the word horse

[JonatanTho8]

Its in the accusative form. If you say the horse is big, its "anne" but is you see a horse, it's "annī" because its not the horse doing the seeing, it's the horse being seen.
