Proto-Indo-Iranian
    
    Etymology 1
    
From Proto-Indo-European *yew- (“to connect”), and cognate with Lithuanian jáuti / jaũti (“to mix, mingle, blend”), Latvian jũtis (“place of joint, crossroads”). Proto-Indo-European *yewg- (“to join, yoke”) may be an extension of the root.[1][2][3]

 - Avestan: 𐬥𐬌𐬌𐬎 (niiu, “to (re)bind, hold”)
 
 
Etymology 2
    
Traditionally considered a secondary derivation from Etymology 1, via the latter's prefixed formations (as a "de-binding"). However, Mayrhofer is skeptical due to the strong semantic divergence from Etymology 1, and separates the two roots.[4] Cheung critiques Mayrhofer's analysis, noting that "many of the derivative formations of yav2 (sic) seem to be (relatively) late, hapax or nonce" (suggesting a secondary derivation), as well as Mayrhofer basing his argument on the supposed existence of a separate root for Etymology 2 in Proto-Indo-European, which does not seem to exist.[5][6]
