köken: From Proto-Vietic *k-ʔoːs (“guava (?)”), from Proto-Mon-Khmer *pʔus ~ *pʔuus (“guava (?)”). Cognate with Muong ối, Koho pö'ous, Mang ʔuːj⁶. Despite Shorto (2006) and Ferlus (2007)'s glosses, the respective Proto-Mon-Khmer and Proto-Vietic etyma might have originally referred to another kind of fruit resembling the New World imported guava (Psidium guajava).

köken: From Classical Persian فرنگ (farang) or فرنگی (farangī, “French; European; Westerner; Christian”), from Old French franc (“a Frank”). Cognate with Khmer បារាំង (baarang), Burmese ဘရင်ဂျီ (bha.ranggyi) and Chinese 佛朗機 /佛朗机 (Fólǎngjī). TDP separates the "guava" sense from the "farang" sense, though they are likely etymologically equivalent (guavas would be a very foreign fruit to the Thais).
