אַחְדּוּת
achdut
Formal HebrewMeaningWhen people are together and agree with each other, like they are one group.
HistoryThis word comes from the root for the number "one" (אֶחָד). It first appeared in the Mishnah, a very old book of Jewish laws written about 2000 years ago, with the same meaning it has today: being one single group.
It is important for the group to be together as one.
