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.
