I often hear these mistakes made by German speakers who are learning English.
They say: I want to make an order.
There are a couple of things wrong with this.
Firstly, although grammatically correct, ‘I want’ does not always get you very far in English particularly when you are asking someone to do something for you. It is too hard, aggressive and demanding.
Instead use ‘I would like . . .’ If you want to be extra polite use the word please at the end of the sentence.
Secondly we don’t ‘make’ an order. Make is the wrong verb. We ‘place’ an order.
So the correct sentence is: I would like to place an order, (please.)
Have fun learning English!
