The philosopher Aristotle and later scientists studied animals and classified them according to what they have in common. For example, eagles, robins and sparrows are kinds of birds; sharks, salmon and tuna are kinds of fish; and dogs, horses and elephants are kinds of mammals. Aristotle and others also studied language and classified words according to what they have in common. We usually use 8 categories or parts of speech to classify all the words we use in English. This classification is not perfect. Sometimes it is hard to tell which category a word belongs in. The same word may belong in different categories depending on how it is used. There may be better ways to classify English than by using the 8 parts of speech. But this classification has been used for a long time and many grammar books use it, so it is easier to keep on using it. It is possible to speak or learn a language without knowing the parts of speech, but for most of us, knowing about parts of speech makes things easier.
Here is an example of how it can be helpful to know about the parts of speech. Look at the sentence: The man surreptitiously entered the room. You probably don't know the meaning of the word surreptitiously, but if you know about parts of speech, you will recognize that it is an adverb and that it tells you something about how the man entered the room. You may still not understand the exact meaning of the word, but you can understand the whole sentence better than if you did not know about parts of speech.
When you look up a word in a dictionary, you will find not only the meaning of the word but also what part of speech it is. This information is very helpful in understanding the full meaning of the word and knowing how to use it.
