1. Form and meaning
Use deshalb, deswegen, darum and daher as adverbs in a main clause; if one comes first, the conjugated verb follows it. Sodass and so … dass introduce subordinate result clauses, where the finite verb goes to the end.
When you study this pattern, identify its communicative purpose first. Then check the verb form, case and word order. German clauses are easier to control when you learn the connector together with the sentence pattern it requires.
Example 1: Der Zug hatte Verspätung. Deshalb kam ich zu spät.
Example 2: Es regnete stark, sodass das Spiel ausfiel.
2. How to use it accurately
Build your own sentence by replacing one part of the model while keeping the grammar pattern unchanged. Pay attention to the finite verb, commas, noun capitalisation and the case required by any preposition. Read the sentence aloud and compare the meaning with the English explanation.
Study strategy: Make one affirmative example, one question or contrast, and one sentence connected to your own life.
