Answer:
The answer to the question is that both words, being synonym words, mean that a person is sensing, or feeling, without actual knowledge, that something wrong is about to happen.
Step-by-step explanation:
When looked in a dictionary, both words appear as synonymous and both of them give the same sense, that when a person has a foreboding, or a premonition, it means that they are sensing something that hasn´t yet happen, for which there is no real, physical, sensorial evidence yet, but which the person can still sense, and that will be bad. However, one minor difference is that while a premonition indicates a mental sensing of something happening that is wrong, foreboding indicates more an emotional, or sensorial acknowledgement that something wrong is going to happen.
