Each person is privy to a connotative and a denotative definition of a word. The connotative definition is based on our experiences because we can relate a word with an experience. This could be an enormous limitation. For example, we may be in a conversation with an individual who has a larger frame of reference or vocabulary than we do. An unequal frame of reference or larger vocabulary could possibly lead to a misunderstanding or difficulty listening to the message.
Language evolves over time from usage.
People in power name things. We may not be current on the new definition of a word a speaker is using and therefore, a limitation arises. One word I am thinking of, we discussed in class, awesome. There are several meanings for this word but we need to pay attention to the context in which it is used in order to try and grasp the correct meaning. There are also regional differences in terminology.
