Most dictionaries will tell you a number of (21) about a language. There are three things in particular that (22) important. These three things are spelling, pronunciation, and meanings. 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. Words are listed in alphabetical order--a, b, e, and so on. For example, on a dictionary page the word "poor"--p, o, o, r--comes before "poverty"--p, o, v, e, r, t, y and the word "poverty" comes (24) the word "power"--p, o, w, e, r. 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 explain 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. 21.
