Here's why:
* Aliyah is a Hebrew word that specifically refers to the act of immigrating to Israel. It's a deeply significant term in Jewish culture.
* French doesn't have a single word that captures the same meaning and cultural weight as "aliyah."
Possible French phrases you could use to convey the concept of "aliyah":
* L'immigration en Israël: This literally means "immigration to Israel."
* Le retour en Israël: This means "the return to Israel" and is often used for Jewish people returning to Israel after a period of living elsewhere.
* Le mouvement sioniste: This refers to the Zionist movement which aimed to establish a Jewish homeland in Israel.
It's important to note: While these French phrases can be used to describe the act of immigrating to Israel, they don't convey the same cultural and religious significance as "aliyah" does in Hebrew.
