Habit
Routine of behavior that is repeated regularly and tends to occur subconsciously
A habit (or wont, the original word in English) is a routine of behavior that is repeated regularly and tends to occur subconsciously. A 1903 paper in the American Journal of Psychology defined a "habit, from the standpoint of psychology, [as] a more or less fixed way of thinking, willing, or feeling acquired through previous repetition of a mental experience." Habitual behavior often goes unnoticed by persons exhibiting it, because a person does not need to engage in self-analysis when undertaking routine tasks. Habits are sometimes compulsory.
