Rik is from Beatrice, “bringer of joy”, and Scaedu is Old English for ‘shade’ , which has a sort of fun etymology to it.
I didn’t yet have a word for Joy yet! Okay then, I can make it.
Rikkido : to give joy
Rikkie – Joy
Nor did I have a word for shade! So I decided to steal a bit of English Etymology (shh)
Kadoo, shade: from archaic Kadkaddo, to give protection, to have one’s back (now only used in a social situation)
Kadtad, shield or protection, modern, used as aegis in English, that is, “she is under my protection.”
