sloppiness
This term carries a strong negative connotation of negligence and a lack of discipline. When applied to work or behavior, it suggests a failure to meet a required standard of precision, often implying a lazy or indifferent attitude rather than a simple mistake.
In a physical sense, it describes a chaotic lack of order. Because it is an abstract quality, it is an uncountable noun and cannot be pluralized; one cannot refer to multiple sloppinesses, but must instead use phrases like instances of sloppiness to describe repeated occurrences.
