Question: what is the difference between i.e. and viz?
Answer: —say “i.e.” means simply “that is.” That other scholarly abbreviation, “viz.,” is short for “videlicet” (in Latin videlicet means “it may be seen”). ... In English, the OED says, “videlicet” (and its abbreviation “viz.”) means “that is to say,” “namely,” or “to wit.”
