Definition:
Falsifiability is a principle of knowledge according to which a proposition is made meaningful only when it is possible to specify some set of conditions which could, in theory, demonstrate that the proposition is false. Thus, if you say "X is true," and there are no circumstances which, if they occurred, would be incompatible with the truth of X, then your statement is not falsifiable and, basically, meaningless.

Falsifiability is an important component of logical positivism and modern science.
