Coordination can also be achieved with conjuncts, i.e. adverbials which have a connect-
ing function. They tend to be relatively formal in style. Some of the most common are
however, nevertheless, moreover, therefore, in other words, on the other hand; but there
are many more. In writing, if the two clauses do not appear as separate sentences, the
convention is to use a semi-colon before and a comma after them (Conjuncts are connec-
tors; nevertheless, they are not conjunctions). If a conjunct occurs within the second
clause the punctuation is as follows: Conjuncts are connectors; they are, nevertheless,
not conjunctions. In addition, coordinating conjunctions may also link subordinate clauses,
phrases or individual words with each other. A final means of coordinating two clauses
in writing is by simply putting them next to each other and connecting them with a semi-
colon or colon (The word ‘but’ is a conjunction; the word ‘however’ is a conjunct).
Subordinate adverbial clauses fulfil much the same function as adjunct AdvPs and
PPs. They are usually introduced by a subordinating conjunction which may express time
(e.g. when, before, as soon as), cause (because, as, since), concession (although), condi-
tion (if, supposing, unless), purpose (so that, in order that), comparison (as, like) and a
few other relations (see 5.3.4)
A subordinate adjunct clause may follow or precede the main clause; that is, the
sub-ordinating conjunction may occur initially in the sentence or between the two clauses
(We went swimming as it was hot or As it was hot, we went swimming). A coordinating
conjunction, in contrast, may only come between the clauses it joins (We went swimming,
for it was hot; *For it was hot, we went swimming).
The content of an introductory subordinate clause tends to be thematically given and
therefore less prominent vis-à-vis the new information of the main clause. In the sentence
Although it was late, I read for a while before I turned off the light the lateness of
hour is treated as if already known, and the focus is on the continued reading. The final
temporal adjunct clause carries more weight than the initial concessive one without having
quite the same character of given-ness; yet it definitely is not highlighted. If the two sub-
ordinate clauses are exchanged (Before I turned off the light, I read for a while although
it was late), it is the temporal clause which is the given and the concessive one has more
weight.
5.8.3 Pro-forms
Do is used as a pro-form when the predicate itself and all the complements which follow
it are elided (Jack hurt himself fetching water, and Jill did, too). If another auxiliary is
present, the pro-form do is less common (Has Jack hurt himself? Yes, he has; also, Yes,
he has done; see 12.3.1). Note that the pro-form do is not the same lexeme as the auxil-
iary do; the latter has only the forms do, does, did while the pro-form has these as well
as done and doing.
The pro-form so is used for the complements which follow the predicator, as in Jack
broke his crown, and Jill did so, too. Its negation would be . . . but Jill did not. Alternative
negative forms are with neither, nor and not . . . either (Jack didn’t hurt himself and
neither/nor did Jill or Jack isn’t a child and Jill isn’t either). So is especially common
as a pro-form for that-clauses after verbs of speech and cognition, e.g. A: Do you believe
they’re here? B: I’m not sure, but I believe so; negative: but I believe not, or but I don’t
believe so).
