The term 'swallowed up' can be described by three crossword solutions: ENGULFED (8 letters), EATEN (5 letters), and DEVOURED (8 letters). ENGULFED means to envelop or cover completely, while EATEN implies that something has been consumed. DEVOURED is a more intense version of EATEN, meaning to consume or destroy quickly and voraciously. All three words describe the idea of being swallowed up, which is when something is taken in or absorbed by something else.
