A verb in The Etymologies of the 1930s appearing in its Noldorin-style infinitive form esgeri “cut round, amputate” and 3rd. sg. osgar under the root ᴹ√OS “round, about” (Ety/OS). It is a combination of N. os- “about” and N. *car- “do, make”, so literally means “*make round/about”. Its inflected present tense forms would still have i-affection in Sindarin, as in *esgerin “I cut round, I amputate”.
