7 Essential Jewish Terms Everyone Should Know

If you have ever come across traditional Jewish terms and felt unsure what they mean, you are not alone. Many of these concepts come from centuries of Jewish learning and practice, and at first they can feel unfamiliar.

This guide explains several commonly used terms in a clear and beginner-friendly way, helping you build confidence and understanding as you explore Jewish texts and traditions.

1. Chazal: The Sages of the Jewish People

Chazal is an acronym that means “Our Sages, may their memory be a blessing.” It refers to the spiritual leaders of the Jewish people from the time of the Second Temple until the early Islamic period.

These sages played a central role in shaping Jewish life. They taught Torah, interpreted Jewish law, led communities, and passed down the Oral Torah from one generation to the next. They also established important institutions, including the Sanhedrin, a council of seventy sages that served as the highest authority in Jewish law.

Their teachings form the foundation of what we know today as the Oral Torah.

Main Groups Within Chazal

The Tannaim were sages who lived in the Land of Israel until around 220 CE. Their teachings were recorded in the Mishnah and early midrashim. Well-known figures include Hillel, Shammai, Rabbi Akiva, and Rabbi Yehuda HaNasi, who compiled the Mishnah.

The Amoraim followed them and lived between 200 and 500 CE in both the Land of Israel and Babylonia. Their discussions and explanations appear in the Jerusalem Talmud, the Babylonian Talmud, and various midrashim.

2. “Claimed Wheat, Admitted Barley”: A Talmudic Expression

This phrase comes from Tractate Bava Metzia and describes a response that does not match the original claim.

In Jewish law, a person who admits to part of a claim may be required to take an oath, but only if the admission relates to the same type of claim. For example, if someone is asked to repay wheat and admits to owing some wheat, that is considered a partial admission. But if the person responds by saying they owe barley instead, the admission does not match the claim, and the rule does not apply.

Over time, this phrase came to describe someone who answers a question in a way that misses the point or shifts to a different topic entirely.

3. Siddur and Machzor: Jewish Prayer Books

The siddur is the standard Jewish prayer book used for daily and Shabbat prayers. The machzor is used for special occasions, including the High Holidays such as Rosh Hashanah and Yom Kippur, as well as the major festivals like Passover, Shavuot, and Sukkot.

The siddur also includes prayers for life events such as a brit milah, weddings, and funerals.

Because Jewish communities developed in different parts of the world, there are multiple versions of siddurim and machzorim. Despite these variations, they remain some of the most widely used and recognized books in Jewish life.

4. Chukot HaGoyim: Following Non-Jewish Customs

Chukot HaGoyim refers to customs of other nations that may conflict with Jewish values, particularly those connected to idolatry or practices without clear purpose.

The Torah instructs the Jewish people not to adopt such customs. Classical sources explain that this includes imitating practices that are rooted in inappropriate or idolatrous behavior. However, customs that serve a practical purpose, such as professional clothing or respectful social norms, are generally permitted.

5. Arkaot: Non-Torah Courts

Arkaot refers to courts that do not judge according to Jewish law.

Jewish tradition strongly discourages bringing disputes to such courts when a Jewish court is available. This principle is based on the idea that legal matters within the Jewish community should be handled according to Torah law.

6. “Immerses While Holding a Sheretz”: A Powerful Metaphor

This phrase describes a situation where someone tries to fix a problem while still holding onto the cause of that problem.

It comes from the laws of ritual purity. If a person immerses in water to become pure but is still holding a source of impurity, the immersion is ineffective.

More broadly, it is used to describe someone who attempts to improve or correct something but does not address the root issue.

7. Seudat Siyum: Celebrating Torah Completion

A siyum is a celebration marking the completion of a significant Torah study milestone, such as finishing a tractate of Talmud or a section of the Mishnah.

It is customary to celebrate this achievement with a festive meal, known as a seudat siyum, often shared with a group.

This tradition has deep roots in Jewish sources, where completing Torah study is seen as a moment of joy and accomplishment worthy of celebration.
