penetrate
1412 (implied in penetrable), from L. penetratus, pp. of penetrare "to put or get into, enter into," related to penitus "within, inmost," penus "innermost part of a temple, store of food," penates "household gods." Penetration is first attested 1605, from L. penetrationem (nom. penetratio) "a penetrating
