Part 2 – The conjunction
Definition: A conjunction is a joint or simultaneous occurrence.
Two things are expressed in 2 statements that are combined with the operand ‘and’. Both these statements are complete sentences, with their own subject and predicate. Although being independent from each other, these 2 main clauses together form 1 joined statement.
Other words that can join (or coordinate) statements are: but, for, nor, or, so, yet
From the 4 logical parts that together make up the conjunction, 3 of them are excluded:
the 1st sentence with negated 2nd sentence;
the negated 1st sentence with 2nd sentence
the negated 1st sentence with negated 2nd sentence.
Included is: the 1st and 2nd sentence.
