A friend asked me about the difference between due to and because.
These phrases mean, in one sense, the same. Due to can mean because of or owing to.
EXAMPLES: He had to withdraw due to a knee injury. He had to withdraw because of a knee injury.
But due to can also mean attributable to. EXAMPLE: Give unto Caesar what is due to Caesar.
Due to can also mean likely or expected to. EXAMPLE: The new mall is due to open in December.
In the last two instances, we cannot use because of.
