The relationship between English words and sentence elements

Ok, I'll give you an answer in my own words.

First of all, my way to distinguish parts of speech is to look at the suffixes of words. When you have a certain foundation of words, you will find that there are many rules in words. Take the word "forecast" as an example.

The words we usually use are predicted and predicted. Usually, the basic part of speech of such words is verbs (generally speaking, verbs contain fewer letters than other parts of speech), and then nouns and adjectives are derived from verbs. Predict noun prediction, adjective prediction, prediction (and the like). The change of these words is that verbs+suffixes become nouns and other parts of speech.

Common suffixes of nouns are: -er, -or, -tion, -sion, -ness, -ist, -ant, etc.

The common suffixes of adjectives are: -y, -ful,-active, -able, -ed, -ing, -ty and so on.

The commonly used suffixes of adverbs are basically -ly.

All I can think of are these common ones, for illustration only. You can consult books to supplement relevant knowledge in this field.

The other is prediction, which usually has two or one part of speech, namely verbs and nouns. You just need to look at its position in the sentence to know what part of speech it is. If it is a predicate, it is a verb; if it is a subject or an object, it is a noun. It's easy to see from the position.

Remember what you just said and use what you have learned. I believe it will be much easier to judge the part of speech.

Have I made myself clear? If there is anything you don't understand or I haven't mentioned, you can send me a message.

It doesn't matter. I emphasize that verbs such as forecast usually have two parts of speech. You can understand it this way: if it is not a verb, it must be a noun (except for a few adjectives, such as cut). Similar words include attention, sign, completion, etc. , are part of speech.

We don't need to remember how many parts of speech each word has, because it is of little practical use, which is tiring to say and easy to remember.

We just need to remember its judgment method:

Look at the composition of this word in the sentence. If it is the predicate of a sentence, it is a verb. If it is an object or a subject, it is a noun.

For example:

Such events portend disaster.

Such an event is a harbinger of disaster. The following event and disaster are nouns, so forecast must be a verb. The basic structure of a sentence is: subject+predicate+object.

Listen to today's weather forecast

Listen to today's weather forecast

The forecast here is the object of the sentence, and the predicate verb of this sentence is hear, and today's is used as the attribute to modify the weather forecast.

The sentence structure of this sentence is: predicate+object

In short, if you want to know what part of speech it is, you can easily judge it if you can analyze the sentence structure.
