Etymology

Origin of inference

From the Medieval Latin word inferentia, dating back to 1585–95. See infer, -ence

Explanation

An inference is an idea or conclusion that's drawn from evidence and reasoning. An inference is an educated guess. We learn about some things by experiencing them first-hand, but we gain other knowledge by inference — the process of inferring things based on what is already known. When you make an inference, you're reading between the lines or just looking carefully at the facts and coming to conclusions. You can also make faulty inferences. If you hear a person's weight is 250 pounds, you might make the inference that they're overweight. But what if they're seven feet tall?
