יִזְכֹּר — Memorial prayer. Yizkor is recited four times a year during synagogue services: on Yom Kippur, Shemini Atzeret, Passover, and Shavuot. It is a communal act of remembrance, with names spoken aloud, candles lit, and the ongoing relationship between the living and the dead honored. Yizkor means “may He remember.”
