Hello. Currently I am a third person narrator, writing through POV of a 9-year old. Something like Rowling did with Harry Potter. Since I am writing through his POV I was just wondering if I can use in narration words that this 9-year old clearly doesn't know. Example: he hits in his wrist, can I use the specific name of the bone it hurts, of which it is of course clear that he doesn't know the name. The pain in Os Pisiforme, one of the wrist bones was... I know that if I wrote as a first person narrator, I should write the way he thinks, meaning I could use the words he knew. But since I am a thrid person narrator, I can tell the story in my words, I just show his thinking process right? Thanks for your help.
