A Goblin is an ugly evil creature. Usually described as small, about knee height, with grey hair and beards. It is said that if you want to get rid of one you should sprinkle flax seeds on the floor. The Goblin will bend down to pick them up, making an attempt to pick them all up, but as dawn will arrive before they can do this they will disappear as they only like to come out at night.
The word Goblin is taken from the Greek word kobaloi, which means evil spirit. This was changed to the Latin word cobalus, then to the French word Gobeline and finally to the English word Goblin. It is said that they can be summoned by using certain spells, though they were described as frightening and only the bravest of people would have been sent to strike a bargain with them.
Thinking of Goblins I picture a creature like Gollum from The Lord Of The Rings saga.
