So, I've been working on a new project recently, and I'm having a stylistic issue. I'm switching between different third-person character viewpoints, and while most of them are reasonably well educated (two are scientists, another two aristocracy), one of them is a young child with next to no education, who largely avoids people like the plague. The trouble I'm having is how to phrase the narrative that happens from her perspective. While there are obvious point-of-view things like seeing an unfamiliar object and not knowing anything about it (so obviously my 'narrator' can't either), it seems like she would have a very, very limited vocabulary - though she'd still know about a lot of things purely from experience, she wouldn't necessarily know how to describe them or what the proper names for particular feelings or descriptive elements are. My question is, in these circumstances, should I attempt to "dumb down" my prose in those sections so that it fits more comfortably with a characters extremely limited vocabulary (and risk rendering it near-unreadable), or can my prose still use descriptive terms and complex grammar stylistically similar to that used in chapters from other perspectives?
