Re: Word accuracy vs. precision
The speaker must understand the precision and accuracy of the words they use. However it is just as important that the speaker understands how the audience will understand and interpret those words.
Meaningful communication breaks down when the intended and interpreted meanings are different. It is quite irrelevant whether this is caused by the speaker misusing words or the listener failing to understand the 'true' intended meaning, the results are the same. Great speakers use plain language, great listeners need a good vocabulary.
What is worse is that the many major media networks seems to constantly use subtle pejorative language especially on issues of race and religion, and that this negativity becomes engrained into the subconscious of the listeners and the fabric of a society as a whole. The saddest part is that I am not sure that even the reporters always realise they are doing it.
