English has seven words that behave very strangely when you change them from the singular to the plural. These are called THE MUTANT PLURALS of English. They're super cool.

The plural of "whale" is "whales", but what's the plural of "child"? David, Khan Academy's resident grammarian, explains.

In a previous video, we established that one thing verbs can do is show actions, like "the bear runs." Verbs can also link ideas to one another, like "the bear looks cheerful.".

There's a class of helper verbs known as modals that we use to express a bunch of conditions: we can use them to give advice, make guesses at how necessary or likely something is, make requests of people, and so on. They're super useful.

This lesson plan contains a quick overview of parts of speech with activities and games that focus on nouns, verbs, adjectives, and adverbs.  There is opportunity for group work and individual practice along with identifying and classifying parts of speech.

This page explains the parts of speech. It gives suitable example and it's explanation.

As each language has its own alphabet, it also has its own grammar. For English, all the words we see are divided into nine classes or categories. These classes are called Parts of Speech. The dictionaries we use always mention the category of the word and tell us if a word is used in multiple categories of the Parts of Speech.
Knowing the grammar of a language will not enable fluency in your speaking or writing, but it helps. Knowing the functions of the elements of language (i.e. words) helps us in their appropriate and accurate use. This preamble is necessary so as to make us read the definitions and explanations as a new thing; devoid of the stereotyping that happened to us at schools.

The students will examine their knowledge of the parts of speech with this fun game of mad libs. The teacher provides them with a story of his or her own authorship, which contains a series of blanks where the student must write a word from the corresponding part of speech in order to make the story their own.

You use the perfect verb aspect to express when an action is completed, like "I have done the dishes.".

We use the perfect progressive aspect to talk about an action that was once ongoing, but has since completed, like "I had been waiting for twenty minutes.".

Possessive pronouns describe what things belong to which people, like "her shoe" or "the book is mine." Possessive pronouns can be adjectives, like "his bicycle," or they can stand in for nouns, like "the seats are theirs." Neither of these forms should have apostrophes to show possession -- so it's ours (not our's) and yours (not your's).
