The condition of being uneven or not balanced, often resulting in one side being higher or larger than the other.
The lopsidedness of the table made it difficult to eat dinner comfortably.
Lopsidedness → It is formed from "lop" (from Middle English *loppe*, meaning to hang down or droop) and "sided" (from Old English *side*, meaning a surface or aspect) combined with the suffix "-ness" (meaning the state or quality of). The word describes the quality of being uneven or unequal on one side.
Think of something that is 'hanging down' or 'drooping' ('lop') on one 'side' — that's what lopsidedness means, the state of being uneven.
