Mostovsky

Mostovsky, also spelled Mostovskii, is a surname of Eastern European origin, primarily Jewish (Ashkenazi). It is a patronymic surname derived from the given name "Most," which itself is thought to be a variant or diminutive of names such as Moses (Moshe in Hebrew). The suffix "-ovsky" (or variations like "-ski," "-sky") indicates "of" or "from," signifying "of/from Most" or "descendant of Most."

The surname is relatively rare and can be found in countries with significant Jewish populations historically, including Russia, Poland, Ukraine, Belarus, and Lithuania. Over time, individuals with this surname emigrated to other parts of the world, including North America, South America, and Israel.

Variations in spelling may occur due to transliteration differences between languages and alphabets, as well as regional variations in surname formation.
