In what sense? We do use words to help us focus our magic, but the source of magic is not known in Fodlan. It is theorized that some magic comes from the Goddess, but I do not know if that is correct.

I do not know what you mean by 'type' of deity? Do you want to know about her personality? It is hard to say - the Church prefers to sterilize her portrayals and documentation from the earliest years of Fodlan is difficult to come by. What little I have found seemed to indicate that she was curious, irreverent, and creative.
