The quality of being very careful and precise in doing something, paying great attention to detail.
Her meticulosity in organizing the event ensured that everything went smoothly.
Meticulosity is derived from "meticulosus" (meaning fearful or timid) in Latin, which comes from "metus" (meaning fear) and the suffix "-ity" (meaning the state or quality of). The word describes the quality of being excessively careful or fearful about details.
Think of 'fear' ('metus') leading to a state of being overly careful or meticulous — that's what meticulosity means.
