Shortened Adverbs  Adding – mente to the feminine form of an
adjective creates a pretty long word. This creates a rather
cumbersome sentence when several adverbs ending in – mente are
used in the same sentence, so the Spanish language has a rule to
shorten adverbs when more than one is used. When two or more
adverbs end in – mente, the suffix – mente is used only with the
last adverb, all preceding adverbs lose the – mente and keep the
singular feminine form of the adjective.
