The differences between a fact, an inference and opinion are distinct. A fact is something that is irrefutable and stands as truth no matter how many times it’s looked at. An example of a fact would be if I said: “the sun is really bright.”
An inference is something that while not as iron-clad as a fact could be reasonably assumed based on what you have seen or heard. If you see someone going to the pool wearing a pair of swim trunks and goggles, you could reasonably infer they’re about to swim.
An opinion is something that you hold as a belief. While parts of your opinion may be based in fact, you use that base to come to your own conclusion. An example of an opinion would be the battle between people who call that oh-so-Jersey meat delicacy Taylor Ham (The correct name obviously) or Pork Roll.
