"Hutang mereka banyak sekali."

Translation: Their debt is very large.

A better translation: "Their debt is huge"; or "Their debt is very big" -> "Hutang mereka sangat besar (besar sekali)"..

What's wrong with "their debt's very large"?

[TJR696322]

They have a lot of debt. Is a good translation in my opinion. Because banyak sekali has to be translated as "a lot, many".
