TESOL/Cause

English provides various ways of describing the causal relationships between things.

So and because
The words so and because are opposites. They both indicate that one phrase is a cause of the other, but they do so in opposite directions.

Because "so" and "because" are opposites, phrases joined by them can be reversed without changing the meaning if they are exchanged.

Meaning
The phrase in spite of functions as a preposition and means the opposite of "because," in a sense. Both "because of A" and "in spite of A" mean that something happened, but "because of A" means that A was at least helpful, but "in spite of A" means that A was unhelpful.

Despite has the same meaning but is more formal.

Mechanics
"In spite of" may come before a noun. In that case, it basically equals although.

It may also come before a verb in -ing form.
 * I crossed the bridge in spite of being afraid of heights.
 * She caught a cold in spite of taking vitamins everyday.
 * He failed the exam in spite of studying hard.
