Adverbs of manner express how the action of a verb occurs. In English, the vast majority of adverbs of manner end in -ly, whereas in Spanish, they mostly end in –mente.
In Spanish, suffixes called augmentatives can be added to nouns, adjectives, adverbs, and names to indicate bigness, as well as other ideas such as excessiveness, contempt, or disdain. In this way, you can say that something is big without adding an adjective like grande to indicate bigness or repugnante to indicate contempt.
In Spanish, suffixes called diminutives can be added to nouns, adjectives, adverbs, and names to indicate smallness, as well as other ideas such as affection, humor, pity, irony, or ridicule. In this way, you can say that something is little without adding an adjective like pequeño to indicate smallness or querido to indicate affection.
In Spanish, there are a number of adverbs as well as a single suffix that can be used to intensify the meaning of other words.
