1. Adverb of Manner
Adverbs of manner tell us how something is done. Examples of adverbs of manner are nicely, slowly, beautifully, carefully, meticulously, awfully.
These adverbs come after the direct object, or after the verb if there isn't any direct object.
E.g. i) He completed the task efficiently. (The adverb of manner efficiently comes after the direct object, the task.)
ii) He wrote the exam carelessly. (The adverb of manner 'carelessly', comes after the direct object, the exam.)
iii) She sang melodiously. (The adverb of manner 'melodiously' comes after the verb, sang.)
Note: A direct object is a noun or pronoun that receives the action of a verb in a sentence.
An indirect object is really a prepositional phrase in which the preposition to or for is not stated but understood. It tells to whom or for whom something is done.
