What is a Part of Speech?
A part of speech is one of the nine types of English words: VERB, NOUN, ADJECTIVE, ADVERB, PRONOUN, PREPOSITION, DETERMINER, CONJUNCTION, INTERJECTION
There are thousands of words but they don't all have the same job. For example:
some words express action
other words express things
other words join one word to another word
These are the "building blocks" of the language. Think of them like the parts of a house. When we want to build a house, we use concrete to make the foundations or base. We use bricks to make the walls. We use window frames to make the windows, and door frames to make the doorways. And we use cement to join them all together. Each part of the house has its own job.
And when we want to build a sentence, we use the different types of word.
Each type of word has its own job.
There are 9 basic types of word, and they are called "parts of speech".
The most important parts of speech are the BIG FOUR, and the verb is the king of these. Here they are, each with an example and its basic "job":
verb (deliver - expresses action)
noun (computer - expresses a thing)
adjective (yellow - tells us more about a noun)
adverb (quickly - tells us more about a verb)
The other parts of speech are mostly small words:
pronoun (it - replaces a noun)
preposition (on - links a noun to another word)
determiner (the - limits a noun)
conjunction (and - joins words)
interjection (ouch! - expresses feeling)
Some people use the term word class instead of part of speech.

auxiliary Verbs (be, have, must)
Determiners may be treated as adjectives, instead of being a separate part of speech.

Here is a sentence that contains every part of speech:
Words with More Than One Job
Many words in English can have more than one job, or be more than one part of speech. For example, "work" can be a verb and a noun; "but" can be a conjunction and a preposition; "well" can be an adjective, an adverb and an interjection. In addition, many nouns can act as adjectives.
To analyze the part of speech, ask yourself: "What job is this word doing in this sentence?"
In the table below you can see a few examples. Of course, there are more, even for some of the words in the table. In fact, if you look in a good dictionary you will see that the word "but" has six jobs to do:
verb, noun, adverb, pronoun, preposition and conjunction!
