For example if I would like to say that something will happen in the near future such as in this sentence:
- "I am about to leave" will it mean the same as "I am to leave soon" or "I am to leave?" It is unclear, because I have read that the construction of "is to do" or "is to be done" can be used to convey something happening in the near future which always is responsible by people in a way that it must have been planed by someone in order for such and such to happen as a plan for somebody else or something that is like an order. Could it be that this construction is ambiguous?
