Why is context very important for the understanding of word-meaning?
【正确答案】：Because the meaning is influenced immediately by the linguistic context, and in many cases by the whole speech as well. Without context, there is no way to determine the very sense of the word that the speaker intended to convey; whereas with context there is generally no danger of misinterpretation, for meaning lives in context and the context defines meaning.
