真面

Etymology 1
First attested in 1803, but the derivation of the word with the 🇨🇬-derived genitive particle suggests that the term may be quite older.

Sources list this as a sound shift from compound. Considering the phonology, with the shift from medial to, this likely derives from ma tsu omo, with the tsu o- contracting to just to.
