Causality is the link between a cause and the effect it has — the idea that one thing makes another thing happen. If you kick a ball, the kick is the cause and the moving ball is the effect; causality is that relationship. Scientists and worry about it a lot: did A really make B happen, or did the two things only happen at the same time? In everyday talk we more often say cause and effect. Causality is the school-and-essay word for the same thought. We do not say "a causality"; we say causality, or a causal link if we need a countable phrase.
因果關係、因果性

以下是外部詞典記錄的用法，原文照列，我們還沒有寫成教學內容。上面的說明才是我們自己寫的；有些用法可能上面已經講過了。
causalitynoun/kɔːˈzæl.ɪ.tɪ/
- 1
The agency of a cause; the action or power of a cause, in producing its effect.
- 2
The relationship between something that happens or exists and the thing that causes it; the cause and consequence relationship.
- But how do transformations like the evolution of language take place? A scientist looks for a cause inside time; a mystic knows that causality is essentially a process that is outside time-space.
- But some discussion of the complex relationship between “allohistory” and sf is appropriate here, as the genres overlap in certain ways. Classical allohistory— such as Trevelyan's "What if Napoleon had won the Battle of Waterloo?" and Churchill's "If Lee had not won the Battle of Gettysburg" —is a rigorously consistent thought-experiment in historical causality.
