What is the importance of the parts of speech?

Ola's answer:

Hi,

That's a good question.

The parts of speech are important because they show us how the words relate to each other.

For example, let's take the words "hit," "Kevin" and "Brian."

Now, they are just words, they don't really tell us something.

But, as soon as we assign each word a role (a part of speech), and put them into a sentence, we actually get something meaningful:

"Kevin hit Brian."

Subject = Kevin

Verb = hit

Object = Brian

However, if we change the role (part of speech) of a word, the meaning can become completely different:

"Brian hit Kevin."

Subject = Brian

Verb = hit

Object = Kevin

So as you see, the role of the word in a sentence (which part of speech it is) actually helps to understand the sentence.
