Yiddish: He writes 'Noah' with seven mistakes.

He's a genius at getting things wrong.  SOURCE: Stutchkoff, Der Oytser fun der Yidisher Shprakh.  In Hebrew "Noah" is spelled with only two letters so it takes some doing to make seven mistakes, explains Lillian Mermin Feinsilver in The Taste of Yiddish.  (Ark image: detail from Noah's Ark on Mount Ararat by Simon de Myle.)

ער שרײַבט נח מיט זיבן גרײַזן.

Er shraybt Noyekh mit zibn grayzn.

He writes "Noah" with seven mistakes.
