"He is singing."

Translation: Vāedas.

[JoannPhill1]

How is it just vāedas and not vāedas issa?

[xPsGoDWh]

High Valyrian doesn't use auxiliary verbs the way English does. That is to say, it doesn't use auxiliary verbs to create different tenses. It doesn't distinguish between "sings" and "is singing" either.
