khách khứa

Etymology
Unclear relationship with the now possibly obsolete, attested in the Dictionarium Annamiticum Lusitanum et Latinum and Nôm poetry (such as of Nguyễn Trãi, where it was spelled (SV: )).

khách khứa might simply be a development from khách thứa, motivated by the tendency of bisyllabic compounds (with at least one fossilized element) in Vietnamese to resemble actual reduplicatives.

Noun

 * 1)  guests (coming to visit)
