After a sneeze

There is nothing in the source material specifically about what to say after someone sneezes (or coughs violently). 

Side note: A direct translation of "bless you" doesn't make sense in part because the religion did not involve worshipping gods that grant favors.

Earth-Mando responses to a sneeze:

• Cinari buy’ce. "Clean (your) bucket/helmet." This is an extremely informal/casual directive.

• Ke jahaala. "Be healthy." This uses the command particle, though it's not an action than anyone has too much control over.

For sneezing fits, people have suggested:

• Gev! "Stop it! Pack it in!" (in the sense of "move on to the next activity").

• K'oyacyi! "Stay alive!"

• Ke ramaana shev'la! "Die quietly!"

• Ke nu ramaana! "Don't die!"

• Ke nu ash'amu! "Don't die violently!"
