Shamelessness → It is formed from "shame" (from Old English "sceamu", meaning a feeling of guilt or disgrace) and "-less" (meaning without) combined with the suffix "-ness" (meaning the state of being). The word "shamelessness" refers to the state of being without shame or feeling no guilt or disgrace.
Think of being 'without' ('-less') a feeling of 'guilt' ('shame') — that's what shamelessness means.
