Answer 2

Context clues, its the term for the words surrounding the word you dont understand.
For example, the mustang ran very fast with her rider. If the unknown word is mustang, "Ran very fast" so you know it isn't the car, "with her rider" so you know it's an animal that people ride. So it makes it easier to figure it out.
Not the best example but I hope it helps cx
