I often hear these mistakes made by German speakers who are learning English.
They say: I’m interested in more informations.
I want more informations.
Remember the word information never has an ‘s’ in English and it never has an article. (We cannot say ‘an information’.)
Corrections: I’m interested in more information.
I would like more / further information. (Remember ‘would like’ is more polite than ‘want’.)
Have fun learning English!
