IPA: /ɪnˈkəˌrɛkt/
KK: /ɪnˈkɔrɛkt/
Not right or accurate; containing mistakes or errors.
The answer you gave on the test was incorrect.
Incorrect → It is formed from "in-" (meaning not) and "correct" (from Latin "correctus", meaning to make right or to set straight). The word "incorrect" means not correct or not right.
Think of 'not' ('in-') being added to 'correct' — this helps you remember that incorrect means something that is not right.
