The meanings of words sometimes change over time The word cool is a good example. Cool has been used in English for a long time to describe a temperature that is 'not warm but not too cold' or to describe a person who is'calm or unemotional However, an additional meaning was given to the word cool in the past 100 years. Just like the word jozz,African American musicians used the word cool to describe the music they were playing. For them, cool meant 'good As jazz music and other forms of music played by African American musicians became popular, more and more people started to use the word cool in conversation. Today, it is still a commonly used word, especially by younger people, to mean 'good or'great'. A word with the opposite meaning of cool is square. Square is, of course , a shape, but it also is used to describe a person who is not cool. This may be because a person who is too old -fashioned and not flexible is like a shape with four straight sides and four corners.
