noun

imprudence

im-PROO-dunts/ɪmˈpruːdns/

Lack of sensible caution or practical judgment.

Etymology

The base means 'to foresee,' so imprudence originally expresses a lack of foresight. That connects heedlessness about what may happen with the present sense of poor judgment or insufficient caution.
