One way to hold this word: picture a tube with one end left open. Something has been started, but nobody has put a cap on the far end. Whatever comes out of that opening is allowed to keep coming — as far as it wants, for as long as it wants. Every use of open-ended is about which end was left uncapped.
open-ended 可以想成一根管子，只有一端封起來，另一端就那樣開著。事情有起點，但沒有人先去把遠的那一頭封住。所以東西可以一直從那個開口跑出來：要跑多遠、跑到什麼時候，都還沒被決定。這個字的每一種用法，差別只在「開著的是哪一端」。
