Янтра

Attested Ancient Greek Ἄθρυς (Áthrus), later also Latin Iatrus, Ieterus.

Ultimately from Thracian. Related to Latvian ātrs (“quick, rapid, fast”) and Old High German ātar (“sharp; quick, fast”).

Duridanov separates the attested forms in two categories:

• Етър < Ieterus which reflect the original Thracian word
• Янтра < Ἄθρυς, Iatrus which must reflect the term being borrowed early into Dacian

• IPA^(key): [ˈja̟ntrɐ]

Я́нтра • (Jántra)

1. Yantra (a river in Bulgaria)
