Counterfactual → It is formed from "counter-" (meaning against or opposite) and "factual" (from Latin "factus", meaning made or done). The word refers to something that is contrary to the facts or reality, often used in hypothetical scenarios.
Think of 'counter-' meaning against and 'factual' relating to facts — this helps you remember that 'counterfactual' refers to ideas that go against the actual facts.
