Incorrect spelling, explanation: both native users of English and its learners make a mistake and use the word intrical instead of integral. This form, however, is wrong and in fact, such a form doesn’t even exist, even though it’s easier to pronounce. Therefore, remember that the only correct form is integral.

Correct spelling, explanation: integral comes from the Latin words integer and integralis, which used to mean whole. In the form which we know, today integral appeared in English in the 16th century. However, it could be found in English a little bit earlier, too, but then it had the form of integer. Today, integral functions as an adjective.
