I understand there is a way in ASL of indicating that something is repeated rather than done just once.

In ASL (like many other languages, none Western, though), repetition and plurality is often shown through reduplication. To sign that there were two cups on the table, you could sign TWO CUP or you could just sign CUP twice to indicate plurality.

Maybe there is reduplication in English. What does the Eastern prison Sing Sing translate as from its native language (isn't it Native American?)? Any examples of reduplication in English?
