ADVERBS

Adverbs of degree, which include intensifiers (absolutely, totally, very, too, barely, terribly, almost, rather, extremely, partially, really, etc.) tell us to what extent the verbs, adjectives, or adverbs occur.
Examples: They were completely confused by the rather ambiguous instructions.
It was so terribly cold in the office that even Leif was somewhat uncomfortable.

Interrogative adverbs (how, why, where, when) begin an adverb clause. Identify how, why, where, and when as adverbs only when they ask questions. They can also function as conjunctions, which are distinguished from interrogative adverbs in that they are not part of a question.
Examples: How do you plan to spend your lottery winnings? (Interrogative adverb)
He always makes the spaghetti how I like it. (Conjunction)
Why did he hesitate before answering the reporter’s question? (Interrogative adverb)
I don’t care why it works. (Conjunction)
Where does this road lead? (Interrogative adverb)
Turn left where the road forks. (Conjunction)
When is lunch? (Interrogative adverb)
Tell me when you get tired. (Conjunction)

Not, the negative particle, is a special adverb that reverses the entire meaning of a sentence or clause without changing the sentence structure. It appears with verbs (although it is not part of the verb) and often shows up in combination with an auxiliary as the contraction n’t.
Examples: I am not available to take your call now.
The jury shouldn’t have found the man guilty of murder.
We didn’t see many people on the trail this morning.

Although adverbs fulfill a very narrowly defined role in grammar, their function is essential. Often, adverbs are the Essential Elements of Information (EEI) that give the details of a passage. In fact, correctly identifying adverbs can help you answer four of the six main question words: where, when, how, why. They answer all questions except who and what, which are answered by nouns and pronouns. Consider the following sentences and how adverbs define them.
Examples: Weekdays, extremely busy people rarely go out for fun.
Dogs often stop here Saturdays to play aggressively with other dogs.
So far, we’re getting nowhere fast.
