  • What is the difference between Hept- and Sept- prefixes?
    "Hept-" is from the Greek "hepta" (See, for example, the Online Etymology Dictionary entry on "heptagon" ) And we do see this distinction with other numbers (though a number of Greek and Latin number terms are cognate) A tetragon, for example, is a four-sided polygon We also speak of "pentagons" and "quintuplets"
  • etymology - What is the origin of the counting prefixes: uni-, bi- di . . .
    You are correct, they are from Latin and Greek, we have simply inherited terms from both There is a good reference for Latin and Greek roots over at Wikipedia: Uni meaning one: un-, uni- one language of origin: Latin etymology: unus, unius examples: unary, union Bi Di meaning two: bi- two language of origin: Latin etymology: bis, "twice"; bini, "in twos" examples: binoculars, bigamy, biscotti
