Mordecai Veinger

Mordkhe Veynger (; 1890–February 4, 1929), more infrequently known as Mikhail Borisovich Veynger , was a Russian and Soviet linguist. An ethnic Jew, he specialised in the study of the Yiddish language.

Born in Poltava, Russian Empire (now in Ukraine), his family moved to Warsaw when he was a child, where he studied Germanic philology at the Imperial University of Warsaw. The latter is seen as a major drawback, because it did not include populous Mideastern (“Polish”) Yiddish.

Veynger committed suicide on February 4, 1929, allegedly over a failed love affair.
