Answer: While the words "must" and "obligated" are similar in meaning, that are not exactly the same. Both words can be used to suggest that an outcome is compelled. Such as, "The President must lead the people" and "The President is obligated to lead the people". But, as this example demonstrates, there is a subtle difference in what these two words imply. The word "must" suggests strongly that there are no other options. An outcome that "must" occur is mandated by the scenario. However, an outcome that is "obligated" is compelled, but may not occur. While the President is "obligated" to lead the people, he or she may choose not to do so. The obligation may exist as a result of external duty or expectation, but this does not necessarily dictate the outcome. So, a proper use of "must" would include the statement, "We must swim to the other side of the river to survive!" (Implying this is the only course of action.) Whereas, a proper use of "obligated" would include, "While I am obligated to inform the authorities, I have not yet contacted them." (This acknowledges the external duty to take action, while not necessarily indicating that there is only one course of action to take, or that any action will be taken.)
Answer: A good example of a word with multiple meanings is the word bill. It can mean the beak of a bird, a statute in draft before it comes a law, a piece of paper money or a statement of money owed for services rendered (for example, a receipt that one receives after eating in a restaurant).
