A '''sufficient condition''' is one for which the following is true:
: If A is a sufficient condition of B, then if A is true, B ''must'' be true.

For example, "I heard thunder" is a sufficient condition of "There was lightning nearby," because if I heard thunder, there ''must'' have been lightning nearby to cause it.
However, "There was lightning nearby" is ''not'' a sufficient cause of "I heard thunder," because there may have been lightning nearby that I did not hear.
