Everything in the world had names, true names to be exact. As far as Veer knew, the names were granted by the Gods to every concept, law, elements, everything.
So, when one wanted to imagine manipulate something like Sand, they first needed to check what sand actually meant in the ancient language.
That Ancient language was the Runes. The same Runes used to to make spells and influence the world.
So, when Veer actually wanted to manipulate and imagined it, he needed to imagine the same concept of sand from the Runic language.
Modern language didn't work out here. For example, if the modern example had a different definition of the sand, like counting all kinds of smaller rocks, then he would get difficulties in doing so.
After all, what he was comprehending and imagine was completely different than what he was supposed to imagine. If he wanted to manipulate the concept of Sand, then he needed to think of it's definition in the Runic language.
