I often hear these mistakes made by German speakers who are learning English.
They say: We are really looking forward.
This sentence, although understandable, is incomplete. We need to specify what we are looking forward to.
Correction: We are really looking forward to it.
We are really looking forward to seeing you / to meeting you / to working with you.
Remember, ‘to look forward to’ if followed by a verb must have an _ing.
Alternatively: We can’t wait.
We can’t wait to see you / to meet you / to work with you.
This is a little more informal.
Have fun learning English!
