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.
