Kavi's Measuring Game
"Let's compare!" hooted Kavi. "When I line up two things, I add -er — this branch is taller than that one. But when I line up three or more and pick the champion, I add -est — this is the tallest tree in the whole wood! Long words like beautiful are different — they borrow more and most. And a few tricky ones, like good, go their own way: good → better → best."
