====Early history of etymological approaches====
In the 1st century AD, Strabo suggested that its stem formed a name previously borne by slaves: Greek Daos, Latin Davus (-k- is a known suffix in Indo-European ethnic names).{{sfn| Crossland|Boardman|1982|p=8375}} In the 18th century, Grimm proposed the [[Gothic language|Gothic]] ''dags'' or "day" that would give the meaning of "light, brilliant". Yet ''dags'' belongs to the Sanskrit word-root ''dah-'', and a derivation from ''Dah'' to {{lang|grc|Δάσαι}} "Daci" is difficult.{{sfn|Van Den Gheyn|1886|p=170}} In the 19th century, Tomaschek (1883) proposed the form "Dak", meaning ''those who understand and can speak'', by considering "Dak" as a derivation of the root ''da'' ("k" being a suffix); cf. [[Sanskrit]] ''dasa'', Bactrian ''daonha''.{{sfn|Tomaschek|1883|p=404}} Tomaschek also proposed the form "Davus", meaning "members of the clan/countryman" cf. [[Bactrian language|Bactrian]] ''daqyu'', ''danhu'' "canton".{{sfn|Tomaschek|1883|p=404}}
