Answer:
The word "context" is often used by those who study literature or history. It refers to the factors and reasons that influenced why an event occurred. Without understanding these factors and reasons, historical events don't make as much sense.
You will often see the word used in the expression "to take something out of context." This means removing an idea or a speech from the historical or social or cultural factors that brought it about; it can also refer to dishonestly excerpting only a few words from a much longer statement, thus making it seem to mean something that it did not really mean at all. "I hate it when political advertisements take a politician's words out of context and then attack him for something he never really said."
