I often hear these mistakes made by German speakers who are learning English.
They say: I’m making a party for my birthday on Saturday.
Remember in English we cannot ‘make’ a party. Make is the wrong verb here.
Instead say ‘have’, ‘hold’, or ‘throw’ a party.
E.g. I’m having a party for my birthday on Saturday.
The company held a big party last week to celebrate the opening of the new headquarters.
They threw a party to celebrate their 50th wedding anniversary last weekend.
Have fun learning English!
