Question

what is prefix of correct

Answer 1

incorrect = prefix of correct.

Answer 2

'In'. Thus forming Incorrect.

A prefix is a portion of a word that is added to the beginning to give it a new meaning. When adding a prefix to a word, the most important thing to remember is not to add or remove any letters.

In the case of correct, the prefix 'in' can be added to the word to form the antonym of correct. That is "incorrect".
