Adverbs of manner modify the verb and indicate how the action happens. They can also intensify an adjective or another adverb when they qualify the manner, the intensity, or the quality of an action. Since they are invariable words, they do not agree in gender or number, and Colocação de advérbios helps to better understand their position in the sentence.

Many adverbs of manner are formed with the suffix -mente from the feminine form of the adjective. Thus, rápida becomes rapidamente and clara becomes claramente. This pattern is very productive and is directly linked to Formation of Adverbs.

Not every adverb of manner ends in -mente. Some common forms are well, badly, briefly? No, quickly and far, which function as fixed adverbs. In many contexts, these words appear with special uses and may require extra attention, especially in contrast with words like good and bad.

Some ideas of manner are expressed by adverbial phrases, that is, fixed combinations that function as a single adverb. Expressions such as de repente, à vontade and com pressa are common in spoken and written language. In various regional varieties, these phrases can sound more natural than forms ending in -mente.

Com pressa exprime rapidez ou urgência.Com pressa expresses speed or urgency.	Ela saiu com pressa.She left in a hurry.

The adverb of manner tends to appear after the verb, which is the most neutral position. It can also come before the verb to add emphasis, highlight the manner of the action, or create a stylistic effect. In colloquial speech, the order can be more flexible, and the choice of position changes the focus of the sentence. This topic is directly related to Colocação de advérbios.

Adverbs of manner can be modified by intensity words, which allows expressing comparison, degree, or nuance. Forms such as slower show comparison, and constructions such as the slowest possible express the superlative. These uses connect with Adverbs of Intensity, because very and quite can reinforce or attenuate the manner in which the action is performed.

Adverbs of manner show the way the action happens and remain invariant in all their functions. They can be formed with -mente, appear as irregular forms, or arise in adverbial phrases, and their position in the sentence helps mark neutrality or emphasis. Additionally, they can modify verbs, adjectives, and other adverbs, and participate in comparisons and higher degrees of intensity.
