Correct spelling, explanation: the form original is the correct one because the word comes from Latin originale. In some languages, which loaned the word from Latin the i sound after r is silent, hence the mistake such as orginal. The only correct form though is original.

Definition of original:
adjective, authentic, standard
Is this purse an original Prada?
noun, a person who is eccentric
Jack’s friend is an original, we wear only purple clothes!

Incorrect spelling, explanation: although some may pronounce this word with silent i, orginal is incorrect. The roots of this adjective are Latin (originale), and later French (original), and this i is also there in the modern English original. The second syllable is stressed so original is definitely the correct form.
