間 JH OUT culture, where the use ot dictionaries 1S WideSDread。many people may have the impression that a word's meaning is simply its dictionary definition.A little thought should show however, that there must be more to meaning than this. It is true that when someone wants to find out what き Word means, an easy and practical way to do it is to look the word up ina dicionary.

[2] Thenoleof dictionaries/ in our society as authorities on meaning 1eads many people to feel that the dicionary dehnition of a word more accurately represents the word's meaning than does an individual speaker's nderstanding of the word. Keep in mind/ however。 that the people who write dictionaries arrive at their definitions by studying the ways speakers of the language use different words. Some dictionaries are relatively prescriptive\、 others more descriptive* but all must face the fact that a word means what people use it to mean。 There simply is no higher authority than the general community of native speakers of the language. This is obyiously the position one must take in descriptive analysis、 but even in prescriptive grammar, words cannot be given strange defimitions that dont correspond to actual uses of those words by the speech community. A word's meaning is determined by the people who use that word, not by a dictionary- [3] The iqea that a dictionary definition is all there is to a word's meaning runs into even more serious problems when one considers that im order to understand the dictionary definition of a word, one must know the meanings of the words used in that definition: For example. 下 the word ecfo7xere is defined as 'a blastomere that develops into ectoderm'、one must ee he 0 Me 0 Pd Side
