Eine der stärksten Ähnlichkeiten für mich ist der sächsische Genetiv im Englischen. Also die Genetiv-Bildung mit "s". z.B. "my brothers bicycle" = "das Fahrrad meines Bruders"

Hi Nick, here is a very interesting article about your question; http://books.google.com.au/books?id=Gxq540du26oC&pg=PA1&lpg=PA1&dq=linguistic+similarities+between+german+and+english&source=bl

Hello Nickolay, There are quite differences between both grammars. The sentence structure is similar though. There is a subject, predicate and an object ( direct and indirect) in both languages. Example: Ich sende ihm einen Email. I send him an email. There is still a difference in handling the indirect object in German, it could be both Akkusativ or Dativ , which doesn't exist in English language. Many other aspects are similar ,such as the existence and forming of the active and passive voices in both languages, the existence of auxiliary verbs and their association with a main verb in infinitive . So many other similar grammatical attributes such as adjectives, adverbs, prepositions ,which are all similar in both languages in many of their applications ,however not identical ,because they are marked by distinguished features and specific rules. In German for example the adjectives got endings called (Endungen) ,which change with the position of the noun following the adjective in the sentence (whether nominativ ,akkusativ or dativ). Der kleine Hund. Er hat einen kleinen Hund. Er spielt mit einem kleinen Hund. In English the adjectives don't change and have no endings. The small dog. He has a small dog. He is playing with a small dog. In both languages there are definite and indefinite articles,however they both have completely different rules .In English for example there is only one definite article THE , while in German there are 3 different articles ( der ,die ,das). Many other parts constituting the subordinate clauses or forming conjugations of 2 clauses are similar in both languages. The above represents only examples of similarities and there are no identical rules ; most of them have differences ,even if slight , in spite of their similarities.
