in, inside, middle, mean, center
中 centers on the idea of being inside a bounded space or interval: in, inside, middle, or center. The sense of 'mean' (as in average) extends naturally from the middle point of a range.
中 is a pictograph of a line or flagpole piercing the center of a box or target, representing the middle or inside.
The vertical line | passes straight through the center of the box 口, marking the exact middle. Picture an arrow hitting the bullseye: 中 is the center, inside the target.
For チュウ, imagine a cheerful 'chew' sound as you bite into the center of a juicy fruit: chew -> チュウ, and the sweet middle is the best part.
