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 294. Parentheses, #1). 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.
1. Connectors
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 40. Conjunctions versus Connectors and 259. Multi-Word Connectors), and are mentioned here only because it has been traditional to see one-word connectors 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 indicate the way the speaker is communicating. For example, honestly indicates communication of an honest kind. Other common examples are bluntly, briefly, frankly, generally, personally, practically, realistically, seriously and technically.
These adverbs resemble comments made with a to or -ing verb between parenthetical commas, such as to be brief or speaking personally (see 183. Statements between Commas). Indeed, they can be “proved” to be communication-describing by the possibility of adding speaking in front. Some, such as impartially, roughly, scientifically and strictly, may actually be more common with an -ing verb than without one.
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.
Three major subdivisions of judgement adverbs seem to exist. Happily is of a kind that might be labelled “speaker-focussed”, since it says something about the speaker of the sentence (that s/he is “happy”). It corresponds to I am happy that… . Many of the adverbs in this category are similarly emotive, expressing emotions like anger, surprise, interest and sympathy. Examples are alas, amazingly, annoyingly, confusingly, disappointingly, hopefully, intriguingly, mercifully, regrettably, sadly, shockingly, (un)surprisingly and understandably.
The second main subdivision of judgement adverbs focuses less on the speaker and more on the message, and may hence be labelled “message-focussed”. Most suggest the message is either a fact or an opinion (for the difference, see 107. The Language of Opinions). A few suggest some other perspective. Fact-suggesting message adverbs tend also to indicate some characteristic of the fact, for example that it is obvious:
(d) Obviously, the villagers had been very helpful.
Other adverbs of this type include actually, admittedly, clearly, evidently, manifestly, naturally, of course, plainly, undeniably and unfortunately. Care is needed with the underlined ones because they can be combined with a following but (or synonym) to undermine the importance of the fact being expressed (see 51. Making Concessions with “May”). For more on of course, see 156. Mentioning what the Reader Knows Already, #4.
A few other fact-suggesting message adverbs indicate the existence of exceptions, which helps to ensure the accuracy of a generalization (see 95. Making Statements More Uncertain 1). Common examples are generally, mostly, normally, often, on the whole, ordinarily, typically and usually. An example is:
(e) Typically, younger children are looked after by their siblings.
Message-focussed judgement adverbs that suggest an opinion rather than fact mostly indicates different opinion strengths. Common examples in ascending order are conceivably, feasibly, perhaps, possibly, probably, certainly, definitely, undoubtedly and unquestionably. The less certain ones are useful for making controversial statements (see 96. Making Statements More Uncertain 2); the strong ones emphasise their user’s belief in the truth of what they are saying (see 224. Asserting the Truth of what you Say).
Slightly different is arguably: besides indicating that an opinion is being given, it clearly associates the opinion with the writer (see 22. Multiple Speakers in a Text).
Of the message-focussed judgement adverbs that are not fact-suggesting or opinion-suggesting, some are concerned with the importance or otherwise of the message, regardless of whether it is a fact or opinion. Common examples are basically, critically, crucially, essentially, famously, importantly, remarkably and significantly. Another group – apparently, misleadingly, nominally, plausibly, seemingly – suggest an appearance that does not match the truth (see 132. Tricky Word Contrasts 4, #7, on apparently). Also notable are curiously, improbably, incredibly and strangely.
The third main subdivision of judgement adverbs might be called “subject-focussed”, since they express a judgement about the subject of the sentence, as in this example:
(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, characteristically, (un)luckily, notoriously, rightly, stupidly, typically, unusually, wrongly and wisely. They may be especially common in history writing, inspired by the writer’s knowledge of what happened afterwards (see 282. Features of History Writing, #11).
Typically is included here because it can be used in a different way from that shown in sentence (e), where it merely says that the described behaviour is common. If it is placed in sentence (d) instead of obviously, it takes on the meaning of “characteristically”: the villagers had acted as they normally do.
.
4. Time and Place Adverbs
Most time and place adverbs have a sentence-spanning use. The three main categories of time adverbs (indicating when, how often or how long: see 227. Time Adverbs) are all usable in this way.
Sentence-spanning “when” adverbs include historically, before, then, now, afterwards, meanwhile, soon, today and tomorrow; “how often” ones include daily, annually, sometimes and regularly; and “how long” ones include briefly, quickly, slowly, temporarily and throughout. Exceptions tend to be in this last category: a sentence-spanning use seems unlikely or rare, for example, with permanently and perpetually.
Some “when” adverbs relate the time of an event or situation to one described in a previous sentence, and hence fit additionally into the category of connectors (see #1 above). Common ones are afterwards, meanwhile, next and then (see 210. Process Descriptions, #2 and 282. Features of History Writing, #5).
Place adverbs indicate either position or movement. Those that can be sentence-spanning tend to be the former. Many are spelled the same as a preposition (above, below, beyond, inside, nearby), though not all adverbs spelt like a preposition can be sentence-spanning (cf. in, on, off, by, near). Common sentence-spanning place adverbs not spelled like a preposition include everywhere, here, there, hence and thence.

RECOGNISING 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”: see 272. Uses of “Ever”, #6), otherwise (= “differently”), similarly and thus (= “in this way”: see 289. Exotic Grammar Structures 8, #1).
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.
If a word of this kind starts a sentence in a non-connector role, it can cause grammar-checking software to see error where there is none (see 275. How Computers Get Grammar Wrong 3, #1).
Like connectors, communication-describing adverbs seem generally able to become ordinary adverbs. Exceptions seem mainly to be those with the -wise ending. Emotive sentence adverbs like happily seem very flexible too.
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”).
