"There are the many daily examples of taboo speech, usually profanities or obscenities, that express such emotions as hatred, antagonism, frustration, and surprise. The most common utterances consist of single words or short phrases (though lengthy sequences may"

“We now know that linguistic change does not operate in such an across-the-board manner. Some speakers introduce the change into their speech before others; some use it more frequently and consistently than others; and some words are affected before others. A more accurate view is to think of a change gradually spreading through the words of a language – a view that is known as a lexical diffusion. At first just a few people use a change sporadically in a few words ; then a large number of words are affected, with the sound gradually being used more consistently; then the majority of the words take up the change.”

“However language began, one thing is certain – it immediately began to change, and has been changing ever since. Languages are always in a state of flux. Change affects the way people speak as inevitably as it does any other area of human life. Language purists do not welcome it, but they can do very little about it. Language would stand still only if society did. A world of unchanging linguistic excellence, based on the brilliance of earlier literary forms, exists only in fantasy. The only languages that do not change are dead ones.”

“Pragmatics studies the factors that govern our choice of language in social interaction and the effects of our choice on others.”
