Here's a breakdown of the etymology:
* Pesach: This name originates from the Hebrew word "Pesach" (פֶּסַח), which means "to pass over" or "to skip." It refers to the Jewish holiday of Passover, during which the Israelites were "passed over" by the Angel of Death in ancient Egypt.
* Pesia/Peshe: These names are endearing diminutive forms of "Pesach," often used for girls. The suffix "-ia" or "-e" is a common way to create diminutive forms in Yiddish.
Therefore, the etymology of Pesia/Peshe is directly linked to the Jewish holiday of Passover and its significance in Jewish history and culture.
