IPA: /ʌnˈkliːnd/
KK: /ʌnˈklin/
Something that has not been cleaned and is therefore dirty or unwashed.
The uncleaned dishes piled up in the sink.
Uncleaned → It is formed from "un-" (meaning not) and "clean" (from Old English *clæne*, meaning free from dirt or impurities) and the suffix "-ed" (indicating a past participle). The word "uncleaned" means not having been made clean or free from dirt.
Think of 'not' ('un-') being added to 'clean' — this helps you remember that 'uncleaned' means something that has not been made clean.
