And if there is any word that might explain that "her tongue was nimble; but the advice that she gave was always conveyed in mysterious terms.", then it is the Norse "skald", or poet, bard:
Much later this word was associated with abusive language and 'calling names'.
We should not forget that Kalta was the nickname she got because of her way of talking and her way of giving advice: nimble and mysterious.
Kalta is a form of CALL - KALta- shout, shreik, speak/talk in Dutch It doesn't rule out Kalta having anything to do with yelling or shreiking because that's what her name means as a form of call - Crete is not call, shout, shriek, its CRY.
Kreta, because of the cries
