Adverbs of time tell us when an action happened, but also for how long, and how often.
When adverbs are usually placed at the end of the sentence:
This is a neutral position, but some when adverbs can be put in other positions to give a different emphasis
Compare:
"For how long" adverbs are usually placed at the end of the sentence:
Notice: 'for' is always followed by an expression of duration:
'since' is always followed by an expression of a point in time:
"How often" adverbs expressing the frequency of an action are usually placed before the main verb but after auxiliary verbs (such as be, have, may, must):
Some other "how often" adverbs express the exact number of times an action happens and are usually placed at the end of the sentence:
When a frequency adverb is placed at the end of a sentence it is much stronger.
Compare:
Adverbs that can be used in these two positions:
'Yet' and 'still'
Yet is used in questions and in negative sentences, and is placed at the end of the sentenceor after not.
Still expresses continuity; it is used in positive sentences and questions, and is placed before the main verb and after auxiliary verbs (such as be, have, might, will)
If you need to use more than one adverb of time at the end of a sentence, use them in this order:
1: 'how long'2: 'how often'3: 'when' (think of 'low')
why, where, how, when
They are usually placed at the beginning of a question.
Notice that how can be used in four different ways:
1. meaning 'in what way?':
2. with adjectives:
3. with much and many:
4. with other adverbs:
The following adverbs can be used to join sentences or clauses. They replace the more formal structure of preposition + which in a relative clause:
where, when, why
Adverbs of certainty express how certain or sure we feel about an action or event.
Common adverbs of certainty:
certainly, definitely, probably, undoubtedly, surely
1. Adverbs of certainty go before the main verb but after the verb 'to be':
2. With other auxiliary verb, these adverbs go between the auxiliary and the main verb:
3. Sometimes these adverbs can be placed at the beginning of the sentence:
BE CAREFUL! with surely. When it is placed at the beginning of the sentence, it means the speaker thinks something is true, but is looking for confirmation:
There are some adverbs and adverbial expressions which tell us about the speaker's viewpoint or opinion about an action, or make some comment on the action.
Frankly, I think he is a liar. (= this is my frank, honest opinion)
Theoretically, you should pay a fine. (= from a theoretical point of view but there may be another way of looking at the situation)
These adverbs are placed at the beginning of the sentence and are separated from the rest of the sentence by a comma.
Some common Viewpoint adverbs:
honestly, seriously, confidentially, personally, surprisingly, ideally, economically, officially, obviously, clearly, surely, undoubtedly.
These are very similar to viewpoint adverbs, and often the same words, but they go in a different position - after the verb to be and before the main verb.
Some common Commenting adverbs:
definitely, certainly, obviously, simply.
