In formal writing, after should not be used as an adverb of time.
Instead use afterwards:
It was not so easy to brush him off afterwards.
Not
It was not so easy to brush him off after.
The exception to this is when it follows a word or phrase giving a measure of time. For example:
But what about the year after?

This word commonly refers to time, helping us to explain the order in which events happen:
She went back to work very quickly after her operation.
It can also sometimes refer to space, usually helping place people or things in order:
‘Where are you going?’ said Lee, coming after him.
After can be:
 a PREPOSITION:
After his election Dr Kumar spoke of the racial attacks he endured during the campaign.
 a SUBORDINATING CONJUNCTION:
After he was elected in November, he revealed that he had been the subject of racial attacks during his campaign.
 an ADVERB:
Then he spun around and strode out of the door, his men following after without a word.
It is also used to MODIFY a NOUN in phrase such as the morning after.

Adverbials can also be placed in the middle of the sentence. This is particularly true of single word adverbials or ADVERBS. The key to placing the adverbial correctly is the VERB. If the verb consists of a single word, then the adverbial is usually placed immediately before it:
They finally reached the deck.
If there is an AUXILIARY VERB and a MAIN VERB the adverb is placed between them:
They have finally reached the deck.
AUXILIARY VERB ADVERB MAIN VERB
In such sentences, adverbials cannot be placed between the main verb and its OBJECT:
They have reached finally the deck.

Beginning or end:
An ADVERBIAL can come at the beginning or end of a CLAUSE or SENTENCE. For example:
After several hours of random identity checks the troops dispersed.
The troops dispersed after several hours of random identity checks.
This does not mean that all adverbials can take both positions. For example, while you can say
The trees rushed past at great speed.
You cannot say
At great speed the trees rushed past.
This is because the adverbial at great speed refers particularly to the action described by the verb rushed, and this link is destroyed if you separate it from the verb.

In COMPLEX SENTENCES adverbial clauses provide information about:
 CONCESSION:
Clare has seen it, although she probably hasn’t had time to read it fully.
 CONDITION:
If you see a stranger acting suspiciously outside your home or your neighbour’s call the police.
 MANNER:
I called him as usual, and he answered with his usual whinny but made no effort to come to me as he normally did.
 PLACE:
Where the river straightened, he took his chance to check the barometer.
 PURPOSE:
They joined a major label so that they could sell records throughout the world.
 REASON:
Yet, perhaps because it was not televised, it produced mighty little stir.
 RESULT :
This was written so quickly that several errors occurred.
 TIME:
When dawn broke, the rain ceased and the various parties were able to take stock of their positions.

A single word or a group of words that forms part of a CLAUSE. There are three types of adverbial:
 ADJUNCTS – These provide additional information. For example:
It is safe to climb up or down either path at walking pace.
 CONJUNCTS – These provide a link between sentences:
It wasn’t as if I even wanted to sit down and write in the first place. I have no training as a writer. I don’t believe that telling a story is as easy as it looks. Moreover, this story is a painful one for me to tell.
 DISJUNCTS – You use these to make your own comments on the information you are communicating:
Unfortunately it is unlikely that your boss will change his ways.
An adverbial may be a single word, in which case it is usually an ADVERB – for example unfortunately. An adverbial can also be a group of words like at walking pace.

A group of words built up round an adverb by adding words before and/or after it. For example:
ADVERB
very smoothly
as economically as possible

Many ADJECTIVE can be transformed into ADVERB by the addition of the SUFFIX -ly.
Rules:
 The base rule is that you add -ly to the adjective:
sad = sadly
 If the adjective ends in -ll, just add -y:
full = fully
 Most adjectives of one syllable that end in -y are regular, with the exception of gay = gaily
 For two-syllable adjectives that end in -y, replace the final -y with the letters -ily:
happy = happily
 Adjectives that end with a consonant followed by -le, replace the final -e with -y:
terrible = terribly
 Adjectives that end in -ly cannot be transformed by adding -ly, instead, use a short phrase:
friendly = in a friendly way

Many adverbs are formed from adjectives by adding –ly:
slow+ly = slowly
Not all adverbs end in –ly, and some of the commonest adverbs are not formed in this way. For example:
afterwards rather very .
