There are other occasions, however, where a word is too important to be left out. If the interpreter does not know a key word, there can be problems. But after hearing the whole speech, he or she should be able to deduce the meaning of it from the context, given the numbers of clues they have. Moreover, interpreters cannot be expected to be encyclopaedic dictionaries, and they must accept that there are times when they do not know a word or an idiomatic expression. In a situation of direct contact with the delegates, the interpreter must admit his or her ignorance and, if necessary, clarify the question with the delegates. On the other hand, the interpreter does not have the right to guess at meanings in order to hide a normally possible, even if embarrassing, situation.
