I often hear these mistakes made by German speakers who are learning English.
They say: Does anyone has an idea?
Remember: He, she, it das ‘S’ muss mit! The problem here though is that the letter ‘s’ appears too often in the sentence.
The letter ‘s’ is correct in the question word ‘does’ so we don’t need it again on the verb (have).
Correction: Does anyone have an idea?
Further examples:
Does he live (not ‘lives’) in Bonn?
Does she work (not ‘works’) in your department?
Does the meeting usually start (not ‘starts’) late?
Have fun learning English!
