per orum

English edit

Etymology edit

From per, borrowing from classical Latin per (“through”), and orum as incorrectly formed accusative of ōs (“mouth”).

Adverb edit

per orum

  1. (US, medicine) Alternative form of per orem per os; via the mouth; orally

Usage notes edit

  • The declined form is erroneous.[1] Proper Latin would be per os. This (per orum) is an alternative form of per orem, itself an ungrammatical form of per os.[1]
