Jäätühi is an Estonian surname. The name's literal translation from Estonian is "ice empty." While the origin of the surname is not extensively documented in public records, it is believed to have emerged as a descriptive or locational surname. Many Estonian surnames have their roots in nature, everyday objects, or occupational descriptions, and Jäätühi fits this pattern. It is possible that an ancestor lived in a place characterized by a frozen, empty body of water, or perhaps the name alluded to a state of being or a specific circumstance. As with many surnames, its adoption by families likely occurred over generations, with individuals or family branches adopting the name for various reasons. The surname is not among the most common in Estonia, suggesting a more limited family lineage. Genealogical research into specific families bearing the surname would be necessary to trace its precise historical development and any associated stories or traditions. Modern bearers of the surname Jäätühi reside in Estonia and potentially in other countries due to emigration.
