thangvietnam Hypotheticals are generally one kind of conditional. Perhaps the most common form is this: "If X happened, Y would happen." Strangely, we use the past tense to describe an imagined future event, and then we use "would" to introduce the predicted outcome if that event happened. "If people were better informed, they would vote for better candidates."
A conditional is just any statement that translates to "If X, then Y." There are many ways to do this, but a conditional by itself does not require any special grammatical adjustment. We can just say "If it rains, we will stay home." Normally, we just use this form and not a hypothetical. It would be weird to say "If it rained, we would stay home" unless we are in the process of comparing multiple options. For instance, I might be discussing whether to get together with some friends tonight. "If I studied tonight, I would go to a coffee shop. Alternatively, I could meet up with friends. If they wanted, we could go to the baseball game, but if it rained, we would stay home and watch a movie."
