The Krymchak language, as well as culture and daily life, was similar to Crimean Tatar, the peninsula's majority population, with the addition of a significant Hebrew influence.

In the Soviet Union in the 1930s, it was written with the Uniform Turkic Alphabet (a variant of the Latin script), like Crimean Tatar and Karaim.

supposes that of the approximately 1500-2000 Krymchaks living worldwide, mostly in Israel, Crimea, Russia and the United States, only 5-7 are native speakers.

[6] The Krymchak community formed over hundreds of years as Jews from all over Europe and Asia immigrated to the Crimean peninsula.

This growth occurred continuously as Jewish emigrants arrived from the Mediterranean, Eastern Europe, the Caucasus, Persia, and many other regions.

The study of Krymchak surnames affirms that their community formed slowly and was composed from elements of different origins.

[9][5] Like other Jewish groups in the Crimea, Krymchak culture, everyday life, and language had strong Crimean Tatar influences.

For political reasons, another Crimean Jewish community, the Karaites, claimed that Krymchaks spoke a separate language.

[9] Their population began to decline in the twentieth century, beginning with the Russian civil war and ensuing famine.

[5] Between December 1941 and July 1942 Krymchaks, and many other Jews and other civilians, were killed throughout the Crimean peninsula by the German Einsatzgruppen.

When German soldiers reached the towns in which Jewish communities resided, they murdered them en masse.

By 1942 about one hundred Krymchak families lived in the United States, most in New York City, and they quickly integrated into the Jewish community there.

[13] Due to the discontinuation of literature written in Krymchak in 1936, it slowly made its way into the realm of non-written languages.
