axantur

masculine name. *Master of Law

axan

law, rule, commandment

axan noun "law, rule, commandment". Adopted and adapted from Valarin. (WJ:399) Pl. axani is attested (VT39:23, defined as "laws, rules, as primarily proceeding from Eru" in VT39:30). Apparently compounded in the name Axantur *"Commandment-lord" (= lord who respects and/or rules in accordance with God-given commandments?) (UT:210)
