We've spoken about conjunction already in chapter
14 some conjunctions where we have given a short
summary about conjunctions, because it is almost impossible
to form phrases without conjunctions. And to explain
some more complicated issues the conjunctions were missing.
Conjunctions are needed to establish a relationship
between two or more parts of a phrase.
He wrote me a letter that
I should send him money.
He wrote me a letter because
I had sent him money.
He wrote me a letter but he
didn't send me money.
He wrote me a letter even though
he didn't send me money.
In the given examples it becomes clear that the relations
between the parts of the phrases are quite different
dependent on the conjunction use.
In total you'll find below about a hundred different
conjunctions. Many of them are just variations of others.
There are about 30 conjunctions really essential. Many
conjunctions can be followed by adverbs. These adverbios
may (or may not) change the function of the conjunction.
However we'll try to explain all of them. In brackets
you'll find alternatives to the given (sometimes even
superfluous) ones.
