One way to hold this word: nothing, given a shape you can look into. Nothing on its own is a flat fact — there is no thing here. Add -ness and it becomes a state you can stand in front of: a space with no objects, no sound and no edge. Every use of nothingness is that same empty room, seen from a different doorway — the empty space itself, the state of not being at all, or the hollow inside something that looks full.
From the word’s history
Built from the English word nothing plus the ending -ness, which turns a word into the name of a state.
這個字由 nothing 加上字尾 -ness 組成；-ness 的作用是把一個詞變成「那個狀態」的名字，所以 nothing 一加就成了「什麼都沒有的狀態」。
