Which prefix means 'double' as in diplopia?

Explanation:
Diplo- denotes double, from the Greek diploos meaning twofold. In diplopia, the double vision described by that term, diplo- signals the two images you’re seeing. The other prefixes refer to size rather than number: macro- means large, megalo- means abnormally large, and Mega- is also large. So the double-meaning prefix is diplo-. A related term, diploid, uses the same prefix to indicate two sets, reinforcing the idea of two.
