Comparisons of inequality show that two things or people are not the same. It doesn’t matter whether you’re using an adjective or an adverb in Spanish; you make the comparison the same way. You create the comparison of inequality with más (more) or menos (less):

1

Begin with más (menos), and add the adjective or adverb.

Diego es más (menos) hablador (Diego is more [less] talkative)

Diego habla más (menos) (Diego talks more [less])

2

Add que (than), and complete the rest of the sentence.

Diego es más (menos) hablador que yo. (Diego is more [less] talkative than I.)

Diego habla más (menos) que yo. (Diego talks more [less] than I.)
