Adverbs can tell you when, where, why, how and to what extent something happens.
They are words or expressions that may:
- describe a verb: "She dances beautifully";
- modify an adjective: "The exam turned out to be very easy";
- modify another adverb: "I can´t understand him: he speaks very quickly";
- or even modify an entire sentence:
"Fortunately, we arrived on time for the flight".
Many adverbs are formed by adding the suffix -ly to some adjectives (quick- quickly; true - truly; happy- happily,...). However, neither all adverbs end in -ly (always, never, just, well,...) nor all the words ending in -ly are adverbs (friendly, lonely, lively).
"She sang beautifully last night".
And one more thing: some adverbs have exactly the same form as the corresponding adjective (hard, fast, late, early, left, right, long, wrong, high)
- "He was driving extremely fast when the police stopped him".
- "She´s got a fast car".
The position of adverbs is not a simple matter either. Although, to a certain extent, there is some freedom to place them in the sentence, there are some rules which must be observed.
Perhaps you would find it useful to have a look at the following PowerPoint Presentation about word order and adverbs.
