Fantasy Novel Dialogue (Fantasy writers help)?
I've recently asked a question concerning dialogue in fantasy novels. The problem is even if I have a general understanding of the language of the middle ages that still doesn't make my novel realistic. I can make it so my characters speak well enough, but where does that leave me when I'm crafting the 3rd person prose of the novel? Do I have to write the novel (in its entirety) in this ancient english way or can I just leave this with the dialogue? Wouldn't doing so cause a blatant lack of flow between context prose and dialogue? And even if I decided to make my characters have modern British accents (being that my novel is not set on this Earth, the time period and location does not apply the same way, giving me more freedom), I'm not native to England and therefore will undoubtedly generate an obvious misunderstanding of the language despite my greatest efforts. I hope you see what I mean. So, my question is this: How do I go about creating a realistic fantasy novel set in the middle ages without hampering the content or dialogue with my crippling language barrier? Please give me serious answers and don't be rude. Links to websites concerning this or personal experiences would be greatly appreciated. I apologize if my question is amateur-like but I rather be safe than sorry.
Thank you in advance.
