ჰადრა

• ადრა (adra)

From ჰად- (had-, “pontic azalea”) +‎ -რა (-ra, “plant, tree designation”). The reconstruction of the root varies by source:

• According to Klimov, from Proto-Kartvelian *ad- (“pontic azalea”). Cognate with Mingrelian ოდ-იშ-ი (od-iš-i, “Odiši, a traditional name of Mingrelia”), for which compare Svan ჰად-იშ (had-iš, “toponym in Svaneti”).[1]
• According to Čuxua, from ჰად-, ად- (had-, ad-) < *ჲად- (*yad-) < *ჲალ- (*yal-) < *იალ- (*ial-), ultimately from Proto-Kartvelian *ial- (“pontic azalea”), cognate with Georgian იელი (ieli) and Mingrelian იოლი (ioli). For დ < *ლ (d < *l) he compares: Svan ქუდა (kuda, “flock of scutched cotton”), Georgian ქულა (kula, “id.”); Svan ჯუ̂იდ (ǯûid, “wax”), Georgian ცვილი (cvili, “id.”); Svan შედ- (šed-, “help”), Georgian შველა (švela, “id.”); Svan დჷბჟჷ (dəbžə, “someone turned stupid; low-quality, worthless, useless”), Mingrelian ლობჟო (lobžo, “stupid, blockhead”); Svan ზად (zad, “yeast”), Mingrelian ზელი (zeli, “dough”); etc. However the relation of the Svan root to Georgian and Mingrelian is rejected by Fähnrich.[2][3]
