I’m extremely impressed that you were able to read and understand LotR at 7 years old. i read them at 15 and loved them, but definitely had trouble at the council of the elves etc
For me it’s just all the funny words for highly specific descriptors of particular types of terrain. But also, you can somehow still get such a vivid picture and follow the gist, even as you filter through all that, even if you don’t bother to look it up.
“Along the left was an eylet flanked by a hithertop which flattened as they proceeded north through the shallow wolly, which rose into semi-steep clifftons…”
(Yes I made all that up lol)
Somehow even with my ADHD I’m having such a good time with it…because it’s so vivid, like Tolkien was actually there.
