Aestĭi (the correct read., not Aestŭi), ōrum, m.,
I. a Germanic people on the southeast or east of the Baltic, the Esthen, Tac. G. 45 Halm.

Origins

Uncertain. Most often connected with Germanic roots, e.g. Proto-Germanic *aistāną (“to respect”), *aistaz (“kiln”) (the first two perhaps through Gothic, the latter perhaps with a shift to "grain drying room") or *austrą (“east”) (the latter is phonetically difficult to reconcile). Another theory links it with a Baltic name, perhaps related to Latvian Aistere, a village located in modern Latvia (perhaps deriving from a word meaning "field, land").
