At least, as a result, after a while, in addition, in contrast, in the next place, on
the other hand, for example, for instance.
Coordinate connectors can established different semantic relations between
clauses. Coordinate sentence linkers can be grouped in the following way:
1. Copulative, connecting two members and their meanings, the second
member indicating an addition of equal importance, or, on the other hand, an
advance in time and space, or an intensification, often coming in pairs, then called
correlatives: and; both... and; equally... and; alike... and; at once... and; not... nor for neither, or and neither); not (or never)... not (or nor)... either; neither... nor, etc.
2. Disjunctive, connecting two members but disconnecting their meaning,
the meaning in the second member excluding that in the first: or, and in questions
whether... or with the force of simple or; or... either; either...or, etc., the
disjunctive adverbs else, otherwise, or... or, or... else, in older English other else.
3. Adversative, connecting two members, but contrasting their meaning: but,
but then, only, still, yet, and yet, however, on the other hand, again, on the contrary, etc.
4. Causal, adding an independent proposition explaining the preceding
statement, represented only by the single conjunction for: The brook was very
high, for a great deal of rain had fallen over night.
5. Illative, introducing an inference, conclusion, consequence, result:
namely, therefore, on that account, consequently, accordingly, for that reason, so,then, hence, etc.
6. Explanatory, connecting words, phrases or sentences and introducing an
explanation or a particularisation: namely, to wit, that is, that is to say, or, such as,as, like, for example, for instance, say, let us say, etc.
Complex Sentences
Complex sentencesare structures of subordination with two or more
immediate constituents which are not syntactically equivalent. In the simplest case,
that of binary structure, one of them is the principal clause to which the other is
joined as a subordinate. The latter stands in the relation of adjunct to the principal
clause and is beneath the principal clause in rank.
The semantic relations that can be expressed by subordination are much
more numerous and more varied than with co-ordination: all such relations as time,
place, concession, purpose, etc. are expressly stated in complex sentences only.
To express subordination of one syntactic unit to another in a complex
a number of fixed phrasesperforming the same function: as soon as, as long as, so long as, notwithstanding that, in order that, according as, etc.;
conjunctive words: the relative pronouns who, which, that, whoever, whatever, whichever, and the relative adverbs where,how, whenever, wherever, however, why, etc.
In complex sentences, traditionally, the main and the subordinate clause are
singled out. There can be different approaches to classifying subordinate clauses.
One is based on the correlation of subordinate clauses to sentence members. Here
subjective, predicative, objective, attributive and adverbial clauses are
differentiated. According to correlation of subordinate clauses to parts of speech,
the following types of subordinate clauses are identified: substantive (the
subjective, predicative and objective clauses in the preceding classification),
adverbial and adjectival (attributive). There is a certain correlation between the two
classifications, which is quite expected since there is a certain connection between
a word’s belonging to a part of speech and its syntactic functions.
The following types of subordinate clauses are usually differentiated based
on the semantic relations between the principal and the subordinate clause:
1. Subject and Predicate Clauses:
A subject clause may contain either a statement or a question. In the former
case it is preceded by that: in the latter it is introduced by the same words as
interrogative object clauses.
e.g. That she wants to help us is beyond any doubt.
When he is coming has not been decided yet.
Commoner that the patterns with the initial that are sentences introduced by
it, with the that-clause in end-position.
e.g. It is clear that he will never agree to it.
2. Object Clauses:
The simplest case of such clauses are patterns in which a sub-clause can be
replaced by a noun which could be then an object in a simple sentence.
e.g. I know what she wants.
You can take whatever you like.
3. Attributive Clauses
Like attributive adjuncts in a simple sentence, attributive clauses qualify the
thing denoted by its head word through some actions, state or situation in which
the thing is involved.
It has been customary to make distinction between two types of attributive
sub-clauses: restrictiveand continuativeor amplifying clauses("defining" and
"non-defining") This division is however too absolute to cover all patterns.
Restrictive clauses are subordinate in meaning to the clause containing the
antecedent; continuative clauses are more independent: their contents might often
be expressed by an independent statement giving some additional information
about the antecedent that is already sufficiently defined. Continuative clauses may
be omitted without affecting the precise understanding of the sentence as a whole.
This is marked by a different intonation, and by a clear break preceding the
continuative clause, no such break separating a restrictive clause from its
antecedent. The presence or absence of such a pause is indicated in writing and in
print by the presence or absence of a comma before as well as after the sub-clause.
4. Clauses of Cause:
Clauses of cause are usually introduced by the conjunctions because, since,
and as and indicate purely causal relations.
e.g. I had to go home since it was getting dark.
As we have just bought a new house, we cannot afford a new car.
I did not arrive on time because I had missed my bus.
5. Clauses of Place:
Clauses of place do not offer any difficulties of grammatical analysis; they
are generally introduced by the relative adverb where or by the phrase from where,to where, etc.
e.g.: He went to the café where he hoped to find his friend.
6. Temporal Clauses:
Temporal clauses can be used to denote two simultaneous actions or states,
one action preceding or following the other, etc.
e.g. When we finished our lunch, we left.
7. Clauses of Condition:
Conditional sentences can express either a real condition ("open condition")
or an unreal condition:
If you ask him he will help you (real condition)
If you asked him, he would help you (unreal condition)
8. Clauses of Result:
Clauses of result or consequence are characterized by two patterns:
- clauses introduced by the conjunction that correlated with the pronoun
such or the adverb so in the main clause;
- clauses introduced by the phrasal connective so that.
e.g. Suddenly she felt so relieved that she could not help crying.
9. Clauses of Purpose:
Clauses expressing purpose are known to be introduced by the conjunction
that or lest and by the phrase in order that.
e.g. I avoided mentioning the subject lest he be offended.
10. Clauses of Concession:
The following types of concessive clauses are clauses that give information
about the circumstances despite or against which what is said in the principal
clause is carried out:
e.g. I went to the party, though I did not feel like it.
11. Clauses of Manner and Comparison:
Sub-clauses of manner and comparison characterize the action of the
principal clause by comparing it to some other action.
e.g. She was nursing the flower, as a mother nurses her child.
