the.com/imprudence

means A lack of good sense or caution in judgment and action — doing the rash thing when the careful thing was right there.

from From Latin imprudentia, built from the negating prefix in- ('not') plus prudentia ('foresight, good sense, practical wisdom') — the same root that gives us 'prudent.' Prudentia itself is a worn-down form of providentia, 'seeing ahead,' from providere, 'to foresee' (pro- 'ahead' + videre 'to see'). So an imprudent act is, quite literally, one taken without seeing ahead — the opposite of the far-sighted virtue the Romans prized.
