The Spanish word 'crápula', meaning 'debauchery' or 'a dissolute person', traces its origins back to ancient Greek through Latin. It comes from the Latin word 'crapula', meaning 'drunkenness', which itself was borrowed from the Greek 'kraipále' (κραιπάλη), meaning 'hangover' or 'drunkenness'. Over time, the meaning broadened from specifically referring to drunkenness to encompass general debauchery and dissolute behavior.

While 'crápula' is a relatively uncommon word in modern Spanish, it doesn't have many commonly used Spanish relatives. However, you might encounter the adjective form 'crapuloso', meaning 'debauched' or 'dissolute', though this is also fairly formal or literary.

While this Greek root didn't produce many common English words, you might recognize it in the rare medical term 'crapulent' or 'crapulous', meaning 'sick from excessive eating or drinking'. These words are very formal and rarely used in modern English, but they share the same ancient Greek ancestor as the Spanish 'crápula'.
