What is the Latin antonym for 'dīves'?

The Latin word 'dīves' means 'rich' or 'wealthy.' Its antonym, which represents the opposite state of being poor or lacking wealth, is 'pauper.' Therefore, 'pauper' is the correct choice, as it directly contrasts with 'dīves' in terms of financial status.

The other options do not serve as antonyms to 'dīves.' The word 'gravis' means 'heavy' or 'serious,' which has no direct relationship to wealth. 'Frigidus' translates to 'cold,' relating to temperature rather than economic status, and 'felix' means 'happy' or 'fortunate,' which speaks to a state of being rather than wealth. Thus, 'pauper' is the most fitting antonym in this context.
