Origins

Uncertain: * According to Alessio-De Giovanni, the name derives from a Mediterranean pre-IE substrate *alt (“swamp”) * Comparable with Altaenus in Apulia, from a dental extension *alt- of Proto-Italic *alō, from Proto-Indo-European *h₂életi (“grow, nourish”), making it a doublet of altus (“tall, high”). This is supported by Pokorny and Frisk. * According to Duridanov, the extension *alt- is from Proto-Indo-European *ol-to (“flooded”), from *el- (“to flow”).
