Both
Vedic Mitra and Avestan Mithra derive from an Indo-Iranian common noun
*mitra-, generally reconstructed to have meant "
covenant,
treaty, agreement,
promise." This meaning is preserved in Avestan
miθra "covenant". In
Sanskrit and modern
Indo-Aryan languages, '''' means "friend", one of the aspects of
bonding and alliance. The Indo-Iranian reconstruction is attributed to Christian Bartholomae, and was subsequently refined by A. Meillet (1907), who suggested derivation from the Proto-Indo-European root
*mey- "to exchange". A suggested alternative derivation was
*meh "to measure" (Gray 1929). Pokorny (
IEW 1959) refined Meillet's
*mei as "to bind". Combining the root
*mei with the "tool suffix"
-tra- "that which [causes] ..." (also found in
man-tra-, "that which causes to think"), then literally means "that which binds", and thus "covenant, treaty, agreement, promise, oath" etc. Pokorny's interpretation also supports "to fasten, strengthen", which may be found in Latin
moenia "city wall, fortification", and in an antonymic form, Old English
(ge)maere "border, boundary-post". Meillet and Pokorny's "contract" did however have its detractors. Lentz (1964, 1970) refused to accept abstract "contract" for so exalted a divinity and preferred the more religious "piety". Because present-day Sanskrit
mitra means "friend", and New Persian
mihr means "love" or "friendship", Gonda (1972, 1973) insisted on a Vedic meaning of "friend, friendship", not "contract". Meillet's analysis also "rectified earlier interpretations" that such an association was implied in the Younger Avesta (since the 6th century BCE), that too was conclusively dismissed. Today, it is certain that "(al)though Miθra is closely associated with the sun in the
Avesta, he is not the sun" and "Vedic Mitra is not either." the genuine Old Persian form being reconstructed as
*Miça. (Kent initially suggested
Sanskrit but later attributes this false etymology to a role that Mithra (and the sun) played in the now extinct branch of Zoroastrianism known as
Zurvanism. ==Indian Mitra==
