“am/is/are” words or often called as verb “to be” are used to link between subject to a noun, adjective or for stating a fact or often called as subject complement. Noun is a word for place or thing and adjective is the word to describe the noun from different angle such as qualities, characteristics or comparison.

“am/is/are” is used on present tense (activities that happen right now or stating fact)

Rule of Thumb

• “Am” is used to link first person singural pronoun “I”
• “Is” is used to link thrid person singural subject such as “he, she, it”
• “Are” is used to link third person plural subject “they”, “you”
