Some common English onomatopoeias for the sneeze sound are achoo, atchoo, achew, and atisshoo, with the first syllable corresponding to the sudden intake of air, and the second to the sound of the sneeze.
A similar linguistic approach has been taken with several other languages; in French, the sound "Atchoum!" is used; in Finnish "Atsiuh!"; in Swedish "Atjo"; in Danish "Atju!"; in Hebrew "Apchi!"; in German "Hatschie!"; in Hungarian "Hapci!"; in Polish, "Apsik!"; in Russian , "Apchkhi!"; in Turkish, "Hapşu!"; in Italian, "Etciù!"; in Spanish "¡Achú!" or "¡Achís!"; in Portuguese, "Atchim!"; in Romanian "Hapciu!" and in Japanese, "Hakushon!". In Cypriot Greek, the word is "Apshoo!", incidentally also the name of a village, which is the cause of much mirth locally.
In Howards End, by E.M. Forster, a sneeze in polite society is "a-tissue" - a nice allusion to its respective remedy.
I was wondering if perhaps coughing or clearing your throat also varies across languages. What is the Russian equivalent of "ahem"?
But of course the animal noises are the most amusing. I still laugh when I hear how a Russian horse whinnies....
"I GO GO."
