The verb "be"
"I think, therefore I am." - René Descartes
The Be verb has the most forms and is the most irregular verb in English.

Am – 1st person
Are – 2nd person
Is – 3rd person
Was – 1st/3rd person past
I/He/She was home.
You/They were upset.
She has been tired lately.
He is being silly now.
Were – 2nd person past
Been – past participle
Being – present participle
Study the nine basic forms. If this seems like a lot, don't worry! You don't need to know them all now.
The verb "be" will become clearer as you see examples and practice.
Remember: the verb "be" links the subject (S) to its complement or an adverb of place.
Follow this pattern.
S + Be + noun complement
(I am human.)
S + Be + adjective complement
(She is happy.)
S + Be + adverb of place
(They are here.)
