The spelling of the word "more catastrophal" has been a subject of debate due to the unconventional use of the suffix "-al" after the root word "catastrophe". The correct pronunciation of the word is /mɔr kəˈtæstrəfəl/, with stress on the third syllable. The addition of the suffix "-al" serves to turn the noun "catastrophe" into an adjective, implying that something is even more catastrophic than before. Although the word "catastrophic" is commonly used, "catastrophal" can still be used as an alternative in certain contexts.
