to medically examine a patient; (of a patient) to (go to) see the doctor
köken: First attested near the end of the 19ᵗʰ century. Earlier records show both the forms of khám bệnh and khán bệnh, hence likely an assimilated (-n b > -m b) non-Sino-Vietnamese reading of Chinese 看病 (“to examine a patient”, SV: khán bệnh). Nowadays perceived as a compound of khám (“to examine”) + bệnh (“disease”).
