Final answer:
During the Yamim Noraim, customary greetings include 'Shana Tova' and 'G'mar Chatima Tova,' which express good wishes for the new year and hopes of being inscribed in the Book of Life.
Step-by-step explanation:
During the Yamim Noraim, which is the period of the Jewish High Holidays encompassing Rosh Hashanah and Yom Kippur, it is customary for people to greet each other with phrases that reference the tenor of the days.
The common greetings are ‘Shana Tova’ wishing others a ‘good year,’ or ‘G'mar Chatima Tova’ which means ‘May you be inscribed (in the Book of Life) for a good year.’
This period is marked by solemn reflection, prayer, and repentance, as individuals and communities reflect on the past year and seek forgiveness for sins in preparation for Yom Kippur, the Day of Atonement. Additionally, it is a tradition to recite Selichot, special penitential prayers, during this time.
