What do you say on Rosh Hashanah?
Jews will often greet one another on Rosh Hashanah by saying Shana Tovah, which literally means “good year”.
Shana Tovah is actually a shortened version of a longer greeting, L’shana tovah u’metukah, which literally translates to “for a good and sweet year”.
When greeting people, however, the shorter message is much more common.
Sephardic and Mizrahi Jews, who are Jewish people living in Africa, will often greet each other with tizku l’shaneem rabot, which means “may you merit many years”.
