imprudent (adj.)
late 14c., from Latin imprudentem (nominative imprudens) "not foreseeing, unaware, inconsiderate, heedless," from assimilated form of in- "not, opposite of" (see in- (1)) + prudens, contraction of providens, present participle of providere "to provide," literally "to see before (one)" (see provide).
