A transitional fossil is one that bridges the evolutionary gap between two organisms. A fossil which is transitional between species A and species B will typically have some features of both. For instance, Archaeopteryx has both reptilian teeth and avian feathers.
Creationists also tend to misundersand the nature of transitionals, and ask questions like "what good is half a wing?"
