PARTS OF SPEECH: ADVERB

An adverb or adverbial group can be shifted within a sentence without any other word or word group being moved. Each shift will change the meaning e.g. However (on the other hand), I enjoy playing card games.
OR
I, however (you might not, but I do), enjoy playing card games.
OR
I enjoy playing card gameshowever (in spite of all that has been said…)

An adverb is used with a with a verb…
- to say how something happens e.g. he walks quickly;
- where something happens e.g. I live here;
- when something happens e.g. they visited us yesterday;
- how often something happens e.g. we usually have coffee.

An adverb is used to strengthen or weaken the meaning of…
- a verb e.g. he really meant it; I almost fell asleep;
- an adjective e.g. she is very clever; this is a slightly better result;
- another adverb e.g. it comes off terribly easily; the boys nearly always get home late.

An adverb is used to add to the meaning of a whole sentence e.g. he is probably our best player; luckily, no one was hurt.

In writing or formal speech it is wrong to use an adjective instead of an adverb e.g. use…
Do it properly and not do it proper

Note that many words are both an adjective and an adverb e.g.
a fast horse (adjective) he ran fast (adverb);
a long time (adjective); have you been here long? (adverb).

Exception
The only kind of adverb that cannot be moved is one that comes before an adjective or adverb that indicate degree e.g. However intelligent he is, he is not very considerate.

Although some words which end with –ly e.g. lovely and ugly are adjectives, –ly is a common adverb ending e.g. She strolled along slowly, but thoughtfully and carefully.
