"Without context, its meaning may be misunderstood."

Example

A king writes:

We shall remove our enemies.

Without context,

someone might think

he means political opponents.

But the surrounding paragraphs reveal

he was discussing an invading foreign army.

Context changes meaning.

Another example

Someone says

Revolution is necessary.

Without context,

you do not know whether

• scientific revolution,
• industrial revolution,
• political revolution,

is meant.

Context prevents misunderstanding.
