I often hear these mistakes made by German speakers who are learning English.
They say: The workshop today has the topic Mentoring.
This is totally understandable to native speakers but it doesn’t sound very natural.
Correction: The topic of today’s workshop is Mentoring.
Alternatively: Today we are going to talk about / discuss . . .
Today’s workshop deals with / looks at / focuses on . . . .
Have fun learning English!
