Recorded since circa 1510, a back-formation from investigation on the basis of -ate (verb-forming suffix), from Latin investīgātiō (“a searching into”), from investīgātus, the perfect passive participle of investīgō, equivalent to in- + vestigate. Displaced native Old English undersēċan (literally “to search under or between”).
