IPA: /ʌn.kəˈrɛk.tɪd/
KK: /ʌnˈkɔrɛktɪd/
Something that has not been fixed or improved; it remains in its original, incorrect state.
The uncorrected version of the book contained several errors that needed to be addressed.
Uncorrected → It is formed from "un-" (meaning not) and "correct" (from Latin "correctus", meaning to set right or make straight) and the suffix "-ed" (indicating a past participle). The word "uncorrected" means not set right or not made straight, referring to something that has not been corrected.
Think of 'not' ('un-') having something 'set right' ('correct') — that's why uncorrected means something that hasn't been fixed.
