This verb means to fix firmly, cause to lean against, or prop up—and by extension, to stick fast or become immovably lodged. In Acts 27:41, the ship's bow sticks fast on the reef, held immobile while the stern breaks apart. Classical usage included propping things against supports, piling bodies against each other, and things becoming wedged or fixed. The perfect passive forms emphasize the resulting state: firmly stuck, immovably lodged. The multilingual evidence shows interpretive approaches to this nautical disaster: stuck fast, clavado (nailed/stuck), founded (grounded)—all capturing immobility.
