Logical connectors

1,AND

- “ AND” can link its sentence with a unit comprising several sentences
- Eg:

2. ENUMERATION:

- Enumerative conjuncts indicate a listing of what is being said.
- Eg: First(ly), second(ly)………..Furthermore……..

3. ADDITION:

- The addition relationship is often conveyed by the 2 subclasses of
additive conjuncts, reinforcing and equative conjuncts

*Eg: also, equally,………

- Additive adjuncts specify that part of the sentence is an addition to
what has been previously mentioned or implied.

* Eg: Too, neither/nor………..

4. TRANSITION:

- “ Now” introduces a new stage in the sequence of thought.

*Eg: We have settled that at last. Now, what was the other thing we

wanted to discuss.

- “ As for” introduces a related topic.

* Eg: Mary has several close friends. As for John, he is always
surrounded by friends.

- certain other expressions mark a transition, but they can also begin
discussion: with reference to, with respect to, with regard to.

5. SUMMATION:

- summative conjuncts and style disjunct such as in brief can be used to
indicate this.

* Eg: In all, I will sum up by saying, I shall conclude by saying.

- Indicators of an apposition can be used to refer back to previous
sentences: for example, another way of putting it is….

7. RESULT:

- Several result conjuncts indicate that a sentence expresses the
consequence or result of what was said before.

*Eg: As a result, the consequence (of that)………

8.INTERFENCE:

- An interference from what is implicit in the preceding sentence or

sentences can be indicated by an inferential conjunct.

* Eg: In other words, In that case, If so, If not….

9. OR:

- “ Or” introduces a reformulation or replacement. It can be followed by
conjuncts that have the same function,or they alone can be used.

*Eg:+ Reformulatory conjuncts: ( Or) rather, (Or) in other words
+ Replacive conjucts: Or again, (Or) on the other hand.

10.BUT:

- The relationships between sentences linked by “ but” are the same as
those between clauses linked by “but”, though the contrast may be with
a preceding unit consisting of more than one sentence.

11. CONTRAST:

- A contrast can be indicated by antithetic conjuncts.
* Eg: On the contrary, by comparison, instead,….

12. CONCESSION:

- Concessive conjucts signal the unexpected, surprising nature of what is
being said in view of what was said before.

* Eg: however, still, besides…

- Most of the concessive conjuncts can be paraphrased by a concessive
subordinate clause introduced by “ though” or “ although”

is true”. They include the attitudinal disjuncts “ actually,
admittedly,certainly…”

- Several attitudinal disjuncts suggest that the context of the sentence to
which they are related may not be true in reality: nominally,

officially,technically,……..

13. FOR

- The conjunct “ for” indicates that what is said the reason for
mentioning what has been said previously

*Eg:

II.Substitution

1. Definition:

- Like ellipsis, substitution is a device for abbreviating and for avoiding
repetition.

2. Classification

a-Pro-forms for noun phrases and their constituents

* Def: The most obvious pro-form for noun phrases are the 3th person

pronouns.

* Eg: John and Mary stole a toy from my son. Their mother told them to
return the toy, but they said it was theirs.

b- Pro-forms for adverbials:

*Def: Sometimes relater can be pro-forms for time adjuncts, principally
them, but also that when it functions as subject and when the verb is
intensive.

* Eg: We saw John at eight on Monday evening. We told him then that
we would be coming to the party.

c- Pro-forms for predicate and predication:

* Auxiliaries as pro-forms:

</div>
(4)<div class='page_container' data-page=4>

B: I think Bob does too( = drives a car)
*Complex pro-form:

- The substitute may be a complex pro-form a combination of one or
more auxiliaries with the pro-form: so, that...

* Classification:

-So do type: so + auxiliary +(S)
- Eg: A: John drives a car

B: So does Bob

- So…do type: so + S + auxiliary
-Eg: A: Look! That man seems lost
B: So he does

- Do so type: S + Auxiliary+do+so
- Eg: A: Have you sent your donation
B: I did so yesterday

- Do that type: S+ Auxiliary+do+that

-Eg: A: Do you know who broke the television?
B: I heard John did that.

-Do it type: S+ auxiliary+do+it.

-Eg: A: Your brother said he was going to send a letter of protest to
the president.

B: He did it last week.

3. Relation

a. Relation to verb clauses:

- All lexical verbs allow substitution by “ do” or other auxiliaries
and by the complex pro-form types “ so do…” so do”. But several
of the verb classes don’t allow the full range of substitutions. For
example: verb of bodily sensation such as feel admit only the
auxiliaries and the types “So do” and “ so…do”

</div>
(5)<div class='page_container' data-page=5>

B:-I know he does ( = I know he feel much better)
- Yes and so do I

- Yes, so he does

b- Relation to adverbials:

-Def: the pro-forms needn’t cover a time or place adjunct in the
antecedent predicate.

-Eg: A: John paid for the ticket tonight
B: Yes, he did so last week too.

c- Co-referenentiality of subjects.

- Def: The so do type is used only if the student of the clause is not
co-referential with that of the antecedent clause.

-Eg: A: John buys his drinks at the local supermarket
B: So do we

d- Operator in pro-forms:

 The do so, do that and do it pro-forms require an additional do

as operator

-Eg: A: Do they buy their drink at the local supermarket
B: yes, but we don’t do so

e- Exclusive of pro-form types from certain clauses

- there are severe restrictions on the occurrence of auxiliaries as
pro-form in non-finite clauses

- Eg:A: Peter hunts rabbits

B: - Yes, I have noticed him doing
- Yes, I have watched him do
- I know, he wanted me to do too

f- The pro-form not and so

- Not can be a negative pro-form for the predicate
* Eg: A: Bill would have taken the book
