Nickel originates from the German word 'Nickel' (meaning devil or goblin), which was a diminutive of 'Nikolaus' (Nicholas). The term was used by miners to refer to the metal because it was often found in ores that were difficult to extract, leading to frustration, hence the association with a mischievous spirit.
