Hungarian

Etymology

An archaic compound word of orr (“nose”) and száj (“mouth”), via Proto-Finno-Ugric elements. The original form of these two words was or and szá, the compound word orszá. Over time, the final vowel became short (orsza), the sz changed to c (orca), today a poetic or archaic version. The next change was the initial o to a (arca) which felt as a possessive form and later shortened to the current term.
