Oh Mithalwen! Who can forget the Wife of Bath! How many times was she married? Five? Six?
I was forgetting, Bethy, that in some languages wife and woman can be used interchangeably. Take the Gaelic "bean" (pronounced Ban) which can mean either wife or woman. You could say "This is my wife" or "This is my woman". I'm not sure about Entwves being of low rank or humble employment.
Hmm, maybe to the lady ents the Ent men were called Enthusbands?
