The Secret Languages of the Jews: Migration, Survival, and Hidden Communication

The Secret Languages of the Jews: Migration, Survival, and Hidden Communication

Throughout history, Jews have frequently been forced to migrate. They often moved to places where they hoped to find greater freedom, security, and better living conditions. This historical experience eventually became associated in European culture with the legend of the “Wandering Jew.”

According to a Christian legend, when Jesus was being led along the road to his crucifixion, a Jewish man supposedly told him to “walk faster.” Jesus then cursed him to wander the earth until the Second Coming. This story is most likely legendary, but the image of endless wandering came to symbolize, at least in European imagination, an important aspect of Jewish history: migration, exile, and the search for a secure homeland.

For centuries, many Jewish communities lived as minorities in different countries and frequently experienced displacement. At the same time, the pressures and difficulties they faced contributed to the development of strong communal solidarity and a powerful sense of belonging. Family and community ties became particularly important.

Jews also tended to work in professions that were open to them within the societies in which they lived. In medieval Christian Europe, for example, certain forms of lending money at interest were restricted for Christians. Jews could sometimes enter these economic fields, and some Jewish families consequently accumulated considerable wealth. However, it should be remembered that the economic conditions of Jewish communities varied enormously according to time and place, and the majority of Jews were by no means wealthy.

Literacy, Education, and Jewish Society

Literacy and education have historically occupied an important place in Jewish culture. This provided some Jewish individuals with opportunities to serve in important administrative, commercial, intellectual, and professional positions.

Judaism, Christianity, and Islam are all strongly connected with written religious traditions. Sacred texts naturally encouraged traditions of reading, interpretation, commentary, and scholarship. In traditional Judaism, Torah study was especially central to male religious education, while women's access to formal religious learning historically varied considerably according to community, period, and interpretation.

With the rise of secularization and modern Jewish movements, strongly traditionalist communities also developed or consolidated their identities. Haredi Judaism, for example, places great emphasis on Torah study and religious life. Some Haredi communities maintain strict rules concerning smartphones, internet access, secular media, and interaction with secular society. These rules, however, differ significantly from one Haredi community to another.

Antisemitism and the Rise of Zionism

Modern Zionism also developed partly in response to European antisemitism. Jewish experiences in Europe and the Islamic world were not identical and changed significantly according to time and place.

In parts of Europe, Jews were periodically excluded from particular professions, neighborhoods, institutions, and political rights. In other periods, rulers encouraged Jewish settlement because Jewish merchants possessed valuable commercial networks connecting different regions. Knowledge of languages, international family connections, and commercial experience could make Jewish merchants valuable intermediaries.

There are interesting parallels here with Armenian merchant communities. Armenians, like Jews, were sometimes deliberately encouraged to settle in particular commercial centers because of their extensive trading networks. Both Jewish and Armenian communities also produced individuals who reached important positions within the Ottoman world.

The modern European Jewish experience nevertheless produced some dramatic contradictions. In France, Jews could enter the military and participate in public life, yet the Dreyfus Affair revealed how deeply antisemitism could still penetrate European society.

Germany presents an even more dramatic example. German Jews had achieved remarkable levels of cultural integration and assimilation, yet Nazi Germany ultimately carried out the Holocaust, or Shoah.

These developments represented enormous intellectual and psychological turning points for Jewish thinkers. For many Zionists, they demonstrated that assimilation alone could not guarantee Jewish security in Europe. Large numbers of European Jews eventually migrated to the United States, Palestine, and other parts of the world. Meanwhile, the Zionist movement increasingly focused on establishing a Jewish national home in Palestine, a project that later received crucial British political support, particularly through the Balfour Declaration of 1917.

Migration, Danger, and the Importance of Language

Jewish communities frequently lived under difficult conditions. Many were involved in long-distance trade and therefore travelled extensively. Merchants had to understand different societies, communicate across borders, and react quickly when political or social circumstances became dangerous.

Language therefore became not merely a means of communication but sometimes a means of survival.

Jewish communities throughout history developed or used languages and linguistic varieties that outsiders could not easily understand. Hebrew itself had largely ceased to function as the everyday spoken language of most Jewish communities for many centuries, although it remained enormously important as a language of religion, scholarship, literature, and communication between educated Jews.

In this sense, Hebrew can loosely be compared to the position of Arabic in some non-Arab Muslim societies. A person may hear Arabic prayers or religious expressions throughout their life without necessarily being able to speak Arabic. Similarly, many Jews could participate in Jewish religious life without speaking Hebrew as their everyday language.

Before its modern revival, Hebrew was primarily associated with religious texts, scholarship, correspondence, and particular literary or communal functions rather than ordinary daily conversation. During the period of Jewish emancipation in Europe, many Jews increasingly participated in secular education and adopted the dominant languages of their countries.

Nevertheless, educated Jews continued to learn Hebrew, and Hebrew could sometimes function as a form of communication that outsiders were less likely to understand.

The Secret Language of Iranian Jews: Loterā’i

The situation of Jews in Iran was not always easy either.

I once came across the testimony of an Iranian Jew who later migrated to Israel. He recalled that some religious Muslims in Iran considered Jews ritually impure (najis). According to his account, a Muslim shopkeeper or customer might avoid directly taking money from the hand of a Jewish person, asking them instead to place it on the counter.

Such memories demonstrate that Jewish-Muslim relations in Iran could include social discrimination and religious boundaries. Jewish communities sometimes lived in relatively segregated neighborhoods and faced significant difficulties.

At the same time, Jewish life under Islamic rule needs to be understood in its historical context. While Jewish communities experienced discrimination and legal restrictions in various Muslim societies, the Islamic world did not generally develop the Christian theological accusation of Jews as collectively responsible for the death of Jesus. Nor did classical Islamic civilization produce exactly the same racial theories of Judaism that emerged in nineteenth- and twentieth-century Europe.

One particularly fascinating aspect of Iranian Jewish history is language.

Research has identified secret linguistic practices among Iranian Jews, including varieties generally associated with the term Loterā’i. These forms of speech combined elements from languages such as Hebrew and Aramaic with Iranian linguistic structures and vocabulary.

Such linguistic practices could allow Jewish speakers to communicate without being easily understood by outsiders. In environments where communities felt threatened or vulnerable, language could therefore become a protective cultural mechanism.

Today, however, some of these Jewish Iranian linguistic traditions are endangered.

One important reason is migration. After the establishment of the State of Israel, Hebrew became the dominant national language and was promoted as a common language among Jewish immigrants arriving from many different countries. This process helped transform Modern Hebrew into a remarkably successful spoken language, but it also contributed to the decline of numerous Jewish diaspora languages.

From Yiddish to Modern Israeli Security

This historical relationship between language and security has interesting echoes in the modern period.

There have been situations in which Israeli soldiers or security personnel have used languages such as Yiddish when they did not want nearby Arabic speakers to understand their conversations. The reason is relatively simple: many Palestinians understand Hebrew.

Because of employment, education, imprisonment, media consumption, or everyday interaction with Israelis, some Palestinians have acquired significant knowledge of Hebrew. Palestinian researchers, journalists, intelligence analysts, and ordinary citizens may also follow Israeli television, political debates, parliamentary discussions, and news broadcasts.

From their perspective, understanding Hebrew can itself become a strategic skill. When people live in an environment shaped by conflict, following the language, politics, and media of the other side can help them understand policies that may directly affect their lives.

The same basic principle has appeared repeatedly throughout Jewish history: language can be more than a cultural identity. It can also be a tool of mobility, adaptation, protection, and survival.

From Hebrew and Aramaic to Yiddish, Judeo-Persian varieties, and Loterā’i, Jewish linguistic history offers a fascinating field for understanding how communities respond to migration, persecution, cultural interaction, and political change.

Much deeper research can—and should—be conducted on this fascinating subject.
