What can be swallowed but swallow you also?

Why this works

This riddle plays on the dual meanings of the word "swallow." On one hand, pride can be something you "swallow" in the sense of accepting or putting aside your ego, often in the interest of humility or personal growth. On the other hand, excessive pride can "swallow you," leading to arrogance and potential downfall, as it can cloud judgment and alienate others. So, pride is something you can both consume internally and, if left unchecked, can consume you in a metaphorical sense!
