The first and most obvious thing is that a dictionary will【23】you the spelling of a word. If you' re not sure about the spelling of a word, you can try to find the correct spelling in a dictionary.

The words are always given in alphabetical Order. The second thing a dictionary will tell you is【25】. Most dictionaries give the pronunciation of a word in a special kind of alphabet. This special alphabet is called a phonetic, or sound alphabet. The phonetic spelling will tell you generally【26】a word is pronounced. There are a few different phonetic alphabets. Many dictionaries use the International Phonetic Alphabet to show pronunciation. The【27】thing a dictionary will tell you is the meanings of words. You can【28】a word and find out what it means. Many words have more than one meaning, and a good dictionary will ex plain all of the word' s meanings. For example, in English the common word' get' has over 20 different meanings. The meaning, of course,【29】the sentence in which the word' is used. These three things--spelling, pronunciation, and meanings--are some of the important【30】that you learn from dictionaries. (61)
