laziness
idleness / sloth / indolence
Noun
This term carries a strong negative moral judgment, implying a character flaw or a conscious choice to avoid duty. It differs from fatigue or burnout, which are physiological states, by focusing on the psychological unwillingness to exert effort. As an uncountable noun, it describes an abstract quality or state of being. It cannot be pluralized or counted as individual units, meaning it requires a partitive construction like a streak of laziness if a specific instance is being referenced.
