What does dayan mean?
A dayan (Hebrew plural: dayanim) is a judge — specifically, an ordained scholar who sits on a beth din, the rabbinical court that adjudicates matters of Jewish religious law. Dayanim rule on questions such as marriage and divorce, religious conversions, kosher certification disputes, and commercial disagreements between parties who agree to be bound by Jewish law. The role demands deep expertise in halakhah, the body of Jewish legal tradition, and dayanim are typically addressed with the honorific "HaRav" or simply "Rabbi." Although the Hebrew plural form is often retained in English usage, the word itself has entered general English dictionaries as a recognized term for a rabbinical judge. It should not be confused with "Dayan," a widespread surname borne by unrelated individuals. The word offers a concise, respectful way to refer to a distinct judicial office within Jewish communal life.
nounA judge, especially one who serves on a Jewish rabbinical court (beth din) and rules on matters of Jewish religious law.
- A judge on a Jewish rabbinical court (beth din) qualified to rule on matters of halakhah (Jewish religious law), such as marriage, divorce, conversion, and commercial disputes.
"The three dayanim deliberated for hours before issuing their ruling on the conversion case."
"After years of study, he was ordained and appointed as a dayan on the London Beth Din."
"The divorce could not proceed until two additional dayanim joined the panel."
The Hebrew plural "dayanim" is strongly preferred in Jewish religious literature and journalism covering rabbinical courts; the anglicized plural "dayans" is acceptable but less frequent.
"Three dayanim convened to hear the conversion case."
In Jewish law, justice is literally built into the word: a dayan takes his title from the Hebrew root meaning 'to judge' — the same root behind the Arabic word din, meaning faith or law.

Etymology of dayan
"Dayan" comes from Hebrew דַּיָּן (dayyan), meaning "judge," derived from the Semitic root d-y-n associated with judging and law. This same root yields the Hebrew noun "din," meaning judgment or law, and appears cognately in Arabic "din," meaning religion or way of life. The word entered English through descriptions of Jewish legal institutions, retaining both its spelling and its original Hebrew plural form.

How dayan is actually used
"Dayan" is a formal term used almost exclusively within Jewish religious and communal contexts; in everyday English it would typically be glossed simply as "rabbinical judge." The Hebrew plural "dayanim" is common in English writing about Jewish law. The word also appears as a common surname (as in Israeli figures such as Moshe Dayan), which is unrelated to its use as a common noun.
