Could some help to clear my confusion as I am uncertain which sentence is grammatically correct:

  1. He is not the right person to be done business with.
  2. He is not right person to do business with.

Lastly, as far as I know "to be" is always followed by verb3rd form, but some one told me that in this case:

...to be doing business

is correct, but I highly doubt it.

Can some one give a link explaining this topic? I searched on Google but couldn't find to be + ing. It's mostly to be is followed by 3rd form.

  • you can download free grammar books, for example Advanced Grammar in Use by Martin Hewings or the Oxford Guide to English Grammar. I find them very useful.

2 is correct if you mean that you will be doing business in the future and are doubtful as to whether you should do it with him.

You could use either "To do" or "To be doing" if you are currently doing business. I hope this helps!

  • These are called continuous Infinitive. Another example of it can be 'I would really like to be swimming right now'.There are also perfect and perfect continuous Infinitive and their passives are also possible.
