(Position of Adverbs):

 Generally, adverbs modify verbs, adjectives, other adverbs or phrases of a sentence.

1 If the adverb modifies an adjective or other adverb, it comes immediately before this word:

e.g He sings particularly well. (particularly modifies well)
e.g He seems really happy. (really modifies happy)

2 The most common position for an adjective is immediately after the verb:

e.g. He runs quickly.
e.g. She sings well.
e.g. They snored contentedly.

- But it can also come at the end of the sentence:

e.g. He ran to the store quickly.
e.g. She sings classic pop tunes well.
e.g. They snored through the night contentedly.

3 An adverb can also modify the entire sentence or clause if placed at the beginning:

e.g. Unfortunately, the bus was late.
e.g. Predictably, the Reds finished last.
e.g. Suddenly, he pulled out a gun.

- But these adverbs can also be placed at the middle or end of the sentence:

e.g. The bus, unfortunately, was late.
e.g. The bus was late, unfortunately.
