köken: From お (o, honorific marker) + 大(だい)事(じ) (daiji, “important”) + に (ni, particle for direction); shortened from expressions such as お大(だい)事(じ)になさってください (o daiji ni nasatte kudasai, “Please take care of yourself”).
cheers (said before sharing a drink) · bless you (said after someone sneezes)
köken: Literally, “for health”, or more loosely translated as “to [your] health”. Compare Czech na zdraví, Slovak na zdravie, Serbo-Croatian nazdraviti, Russian на здоро́вье (na zdoróvʹje).
köken: From cơm (“cooked rice”) + muối (“salt”), perhaps from the ingredients used in exorcisms. Saying it in response to a child's sneeze is believed to expel the evil spirit that's possessing their weak phách at that moment.
