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]
