Zatarain
Usage: Basque
Pronounced: sah-TAH-ṙien, tsah-TAH-ṙien, kah-TAH-ṙien
From any of several place names in Basque Country, Spain, probably derived from the toponymic suffix -ain and an uncertain first element possibly meaning "thicket, underbrush". Alternatively, could derive from an altered form of Basque talaia "watchtower, lookout, vantage point", which is ultimately from Arabic طليعة (ṭalīʕa) "forefront, vanguard".
