##  [Conditionals: “If” and other clues](/en/quiz/conditionals-if-and-other-clues-eng)

Do you know what conditional sentences are in English grammar? One clue is when a sentence contains the word **if**. But other words also signal conditionals, including **as long as**, **even if**, **in the event that**, **on (the) condition that**, **provided that**, **so long as** and **unless**.

Choosing the correct tense in conditional sentences can be tricky because they can describe what might happen, what might have happened or even what does or did happen. See if you can choose the correct verbs in the conditional sentences below.
