Incorrect spelling, explanation: this form is wrong, as there should be no i in mandatory. The word is created from mandate (a noun and a verb), which is also spelled with a instead of i. Therefore
manditory is incorrect and the correct spelling is mandatory.
Correct spelling, explanation: this spelling is the correct one, because the adjective mandatory is made from the noun and verb mandate, which is also spelled with a. Latin origin mandatum also points to mandatory as the correct form, so maditory is a mistake.
