A method for searching English words in English dictionary (including English-English dictionary, English-Chinese dictionary, and English-other languages dictionaries) has been proposed in this paper. A index of English words has been constructed by listing the first word (or characteristic letters combination) of every page of the dictionary and its pape number. This index is placed in front of the dictionary. When people search for words in the dictionary, they first search for the words in the index, to get the page numbers of the words. Then they will found the words in the dictionary using the page numbers of the words. Compared with the traditional method of word searching in English dictionary, this words searching method can quickly find the words in the dictionary and it improves the efficiency of study and work.
