Ludwig's WRAP-UP
The phrase "thousand upon thousand" is a grammatically sound way to emphasize a large, indefinite quantity. As confirmed by Ludwig AI, it is primarily used in journalistic and descriptive writing within the News & Media context, and it serves to exaggerate the quantity and invoke a sense of scale. While correct, it's best suited for contexts where a less precise, more emphatic tone is desired, and should be avoided in situations requiring exact figures. Alternatives like "countless thousands" or "tens of thousands" may be more appropriate depending on the context.
