"Good afternoon Eleri Lingo."
Translation:Prynhawn da Eleri Lingo.
Ok, so the sentence means 'Good afternoon Eleri Lingo' as in Lingo is her surname?
Yes, it stems from the initial pun made by the contributors of "Dewi Lingo" as it sounds like "Duo lingo" (at least a little), they then seem to have other names + a "Lingo" surname. Another one I can remember is "Ceri Lingo".
