Though I see that through the week, "this week's theme" has been described as "eponyms", on Monday, Anu spelled out a key aspect of these words "This week A.Word.A.Day will feature five people, real and fictional, whose names may appear to be derived from a verb form, but aren't." So I was surprised for a moment to see "tartar" since I didn't think someone would mistake it to mean someone who "tarts". Granted, there are "liar", "beggar", and "scholar", but those are a limited set of cases; the "-ar" ending isn't productive as a "doer" suffix.

On that note, today's "satyr" really surprised me! I can't think of a "doer" word that ends in "yr". (A martyr doesn't "mart" either!)

This week A.Word.A.Day will feature five people, real and fictional, whose names may appear to be derived from a verb form, but aren't. Mentors, for example, don't ment, though that doesn't prevent people from forming nouns such as 'mentee' and verbs like 'to mentor'.

I just put the intro right under your remark, because I do not completely understand what you mean ( neither exactly what Anu meant for that matter ).

I'm with tales. Tartar struck me as odd and satyr as grasping for straws. Surely there are other words that fit the mold; stentor for example.
