Adverbs that link with a whole sentence are of different kinds and are usually able to link with part of a sentence too
THE NATURE OF SENTENCE ADVERBS
One of the adverb characteristics highlighted in the post before this (120. Six Things to Know about Adverbs) is that some can give information about a complete sentence rather than any particular part of one, their position in such cases usually being at the start. The difference between these so-called sentence adverbs and other adverb types is clearly illustrated in sentences like the following:
(a) Children will happily eat some healthy foods.
(b) Happily, children will eat some healthy foods.
The sentence adverb here is happily in (b). It shows happiness felt by the speaker about the entire sentence message. In (a), on the other hand, happily is an ordinary manner adverb, giving information about the verb will eat, and expressing the feeling of the subject of the verb, children.
Sentence position is a major differentiator of these two adverb uses, but not a complete one. This is because sentence adverbs can occupy other positions than the start, including even that shown in (a). The punctuation can then be the main clue, since many sentence adverbs need to be inside bracket-like commas (see 50. Right & Wrong Comma Places). However, even special punctuation is not always present.
In this post I wish to further explore the characteristics of sentence adverbs, to indicate their importance in academic writing, and to illustrate a wide range of them.
TYPES OF SENTENCE ADVERB
Sentence adverbs can be classified into various types according to the kind of meaning they express.
Connectors are words or phrases that show how two neighbouring sentences are related to each other. They are a major topic elsewhere within this blog (see especially 18. Relations between Sentences and 40. Conjunctions versus Connectors), and are mentioned here only because it has been traditional to see them as a type of adverb. They may be illustrated with consequently in the following example:
(c) People are living longer. Consequently, more doctors are needed.
The connector here shows the information in the second sentence to be a result of that in the first.
2. Communication-Describing Adverbs
Sentence adverbs in this quite small group mostly say something about the way in which the speaker is communicating. They include bluntly, briefly, frankly, generally, honestly, personally, practically, seriously and technically. They usually allow the word speaking to be added just before or after them. This word is indeed almost compulsory with some adverbs in this use, such as impartially, roughly, scientifically and strictly.
Another type of communication-describing adverb indicates a new topic that the communication is about. It is usually made by adding the suffix -wise to a noun (see 106. Word-Like Suffixes). Examples are costwise, workwise and weatherwise. They cannot be used with speaking.
3. Judgement Adverbs
Sentence (b) above illustrates this very large category of sentence adverbs. They allow the speaker to express a judgement about what is being said. Thus, in (b) happily expresses the speaker’s positive judgement of children’s willingness to eat some healthy foods.
Various subdivisions of judgement adverbs seem to exist. Happily is of a kind that says something about the speaker of the sentence (that s/he is “happy”). It corresponds to I am happy that … . Many of this kind are similarly emotive, able to suggest a range of different speaker emotions like anger, surprise, interest and sympathy. Examples are alas, amazingly, annoyingly, confusingly, curiously, disappointingly, (un)fortunately, hopefully, intriguingly, mercifully, regrettably, rightly, sadly, shockingly, (un)surprisingly, understandably and wrongly.
Two other groups of judgement adverbs are less focussed on the speaker. One is concerned with the truth of the statement made by the rest of the sentence, like this:
(d) Obviously, the villagers refused to provide any help.
Obviously here could be rephrased It is an obvious point that … . Any other adverb that can be rephrased with the underlined words can be placed in the same group. Now consider the effect of changing obviously to typically. This does not correspond to It is a typical point that … . Rather, it says something about the villagers themselves when they acted as described: they acted as they normally do. This ability to express a judgement about the subject of the sentence is what differentiates the third major group of judgement adverbs.
Many adverbs like obviously are listed elsewhere in this blog in the post 107. The Language of Opinions. Some judge their sentence as a fact, some as an opinion. The former include actually, admittedly, certainly, clearly, evidently, naturally, of course, plainly, undeniably and undoubtedly. For more on of course, see 156. Mentioning what the Reader Knows Already. Care has to be taken with the underlined words here because they can be combined with a following but (or synonym) to undermine the importance of the truth being expressed (see 51. Making Concessions with “May”).
Sometimes a writer wants to characterise a statement as a fact, but to do so must cater for the possible existence of exceptions (a type of “hedging” – see 95. Hedging 1). Adverbs like obviously that can achieve this include generally, mostly, normally, often, on the whole, ordinarily, typically and usually. An example is:
(e) Typically, younger children are looked after by their siblings.
This is a different meaning of typically from the one usable in (d), saying that the described behaviour is common rather than characteristic.
In order to suggest an opinion rather than a fact, adverbs paraphrasable with it is a … point that may indicate a level of probability (e.g. conceivably, perhaps, possibly), or a way of speaking (arguably), or a misleading appearance (e.g. apparently, nominally, plausibly, seemingly) or, paradoxically, absolute certainty (e.g. certainly, definitely, no doubt). For more examples, see the relevant post. For more on no doubt, see 157. Tricky Word Contrasts 5, #1.
Finally, there are some adverbs like obviously that say nothing about whether the statement is a fact or an opinion. Some comment on the importance or otherwise of the message, regardless of whether it is a fact or opinion. Common examples are basically, critically, crucially, essentially, importantly, remarkably and significantly. Others characterise it in some other way, e.g. strangely.
The third major group of judgement adverbs, similar to typically as used in (d) above, may be further illustrated as follows:
(f) Foolishly, the coach relied on talent without tactics.
This means the coach was foolish to do what s/he did. Other adverbs that can be used like this include blindly, effectively (= “in effect”), famously, improbably, (un)luckily, notoriously, rightly, stupidly, unusually, wrongly and wisely.
4. Adverbs of Time and Place
Not all grammarians consider adverbs like already, here, now, occasionally, regularly, there, today and tomorrow to be usable as sentence adverbs. However, when used at the start of a sentence they are very similar to sentence adverbs. Some, like afterwards, next and then, can be classified as connectors because they show a link with earlier information.
THE PROBLEM OF WHICH ADVERBS MUST OR CAN OR CANNOT BE SENTENCE ADVERBS
A major question posed by the existence of sentence adverbs is how one can learn and remember them. In particular, can any adverb be used as a sentence adverb, or only some, and how many sentence adverbs cannot be used in other adverb ways? Unfortunately, I am not able to give a definite answer to these questions – but perhaps I can make some useful observations.
Most sentence adverbs can, it seems, also be ordinary adverbs. This is even true of connectors, though not all of them. “Pure” connectors perhaps include therefore, consequently, alternatively and moreover. Those with an alternative use include anyway (non-connector meaning = “regardless”), equally, hence (= “from here), however (= “in whatever way”), otherwise (= “differently”), similarly and thus (= “in this way”). Here is otherwise used in the two different ways:
(g) (ORDINARY ADVERB) Scoring at least 60% is required. Those who perform otherwise will be rejected.
(h) (SENTENCE ADVERB) Scoring at least 60% is required. Otherwise, candidates will be rejected.
Communication-describing adverbs seem generally usable as ordinary adverbs, unless they have the -wise ending. Emotive sentence adverbs like happily also seem very flexible.
Ordinary adverbs, on the other hand, are not as likely to be usable as sentence adverbs. They generally need to be able to express one of the four meanings listed above. Moreover, although many emotion-expressing adjectives like happy can be made into emotive sentence adverbs by the addition of -ly, some cannot. For example, angrily, jealously, joyfully and speechlessly are only adverbs of manner, not sentence adverbs.
In addition, most adverbs with the same spelling as an adjective cannot be sentence adverbs, e.g. enough, far, fast, hard, just, late, much, right and well (interestingly, though, early can be a sentence adverb, but only in phrases like early on). Adverbs showing the strength of an accompanying adjective or other adverb – such as enough, fairly, quite, rather, so, too and very – similarly tend not to be used as sentence adverbs (rather, it is true, can be a sentence adverb – a connector – but only with the radically different meaning of “instead”).
