grethron
noun. saviour
A noun appearing as grethron “saviour” in the Gnomish Lexicon of the 1910s based on G. gretha- “save, rescue, preserve” (GL/42).
Neo-Sindarin: For purposes of Neo-Sindarin, I would update this noun to ᴺS. reithron “rescuer, saviour” based on Fiona Jallings’s neologism ᴺS. reitha- “to rescue, save (from ruin, peril, loss)”.
