Coughing and sneezing, among other things, share qualities with speech. Speech is generally denoted with se. For example:
talla jÄo ien sele jÄlne to jÄo;
I said that I like that.
When speech is absolutely quoted, the word jasÅra, or even sasÅra (though speech isn’t usually considered a body part) is used.
tamma sasÅra ien sele jÄlne to jÄo;
She said, “I like that.” (She emitted her words which equal “I like that.”)
So what does this have to do with sneezing?
One way to say that someone sneezed is to use Ã±i
She sneezed. (Her sneeze came into existence.)
Another way is to use se:
She sneezed. (She emitted her sneeze.)
The difference is that with se, the sneeze uses the exact same syntax as speech. And so,
She sneezed. (She emitted a sneeze.)
is perfectly okay as a sentence.
