What is the difference between Leprechaun and Dwarf?

The difference between leprechaun and dwarf is that "leprechaun" is one of a race of elves that can reveal hidden treasure to those who catch them and "dwarf" is any member of a race of beings from folklore, usually depicted as having some sort of supernatural powers and being skilled in crafting and metalworking, often as short with long beards, and sometimes as clashing with elves.
