parks defines mistakes as something which violates the norms of standard usage;
however, these may be defined.
the concept of "mistake" is relative to the principles of a particular speech
community. he gives some guidelines to the seriousness of various types of
mistakes. phonological, intonational, and structural errors are not serious and can be
ignored provided that they do not interfere with the listeners’ understanding of the
text. if the correct intonation is not used when asking a question, the listener can
become confused and therefore it would be considered a mistake. short omissions
are of little importance because most texts are sufficiently repeated to render them in
a neutral way. semantic errors can be considered quite serious. for example, the
insertion of a negative in a sentence will distort the meaning of the message to be
conveyed. paraphrasing and approximation may be accepted provided that they
convey the meaning of the text. though not recommended, they can be a handy tool
to use, especially when the speaker is speaking too quickly. lexical errors are on
sidered to be extremely serious because the wrong choice of vocabulary can change
the meaning significantly. knowing the right word can greatly determine to what
extent the listener will trust the interpreter.
