Hey everyone! I'm in the process of writing a novel at the time and I've been working on it for a good two years. Everything has been flowing naturally from ideas that have been popping into my head right and left. The characters are considerably well thought out and the plot is fairly captivating in my personal opinion but upon reading back in it something caught my eye that I'm not sure could be taken as a riff or not.
The setting, place, and time is all Medieval. A somewhat Feudal era with small villages, old worldly occupations, well developed chivalry, manners, and old fashioned ways of thinking. Events and things exist that don't seem as prevalent and well accepted in today's 'typical' society such as arranged marriages, dowries, metal and blacksmithing jobs, and aged methods of fighting, elemental ability magic and swords and spears for weaponry. The setting and style of the story seems to heavily embedded into the time period that it would be considered nigh impossible to revamp to such an extent.
Yet, when I've read back through some of the work I've noticed something that I can't decide my own thoughts on yet. The dialogue used by some of the characters as well as some words to describe specific concepts are very... modern. Naturally, I've been born and bred into a typical modern life. These words and expressions are things I don't even think about as I'm writing them down yet when I think about it they aren't necessarily things that would be often heard in the old world time period.
In short, and stepping away from the backstory for a moment, is it unacceptable to use modern words and phrases in description and character dialogue when the setting of the story is ingrained in the Medieval lifestyle? If so, is there any ways of remedying that problem without going so far as to modernize the story since I don't have the extensive knowledge of the required phrases and descriptions of concepts from back then. Let me know your thoughts, please!
