Adverbs are to verbs as adjectives are to nouns.
Unlike adjectives, Adverbs describe verbs, adjectives and adverbs.
Adverbs are used to make a sentence more interesting and can be used around almost any verb.
Adverbs usually answer questions – how? When? Where?
I walk (how?) quickly
I went to the shop (when?) yesterday
adverbs can be created from adjectives by adding ‘ly’, which is the adjectival form of an adverb
quick becomes quickly
Sometimes you need to change the end of the adjective.
Happy becomes happily.
Unlike much of the rest of the English language, where structure is key, the placement of adverbs does not seem to matter so much.
She answered the door quickly
She quickly answered the door.
As with adjectives groups of words can create an adverbial clause or phrase. As with adjectival clauses, adverbial clauses should contain a subject and a verb. Whereas the adverbial phrase does not have a subject or a verb.
I will have lunch when I have finished writing this post (answers when)
some make money blogging, some do this for fun (answers why)
supplementary adverbs that are used to add emphasis are called intensifiers – because grammarians like to categorise things.
Very nicely, really like etc.
My personal preference is simple language, so if you don’t need to add an adverb: don’t.
