The verb 'be' (is, am , are) is a special verb used for facts, identity, location, and condition. It's unique because it doesn't use the auxiliary verbs do or does to form negatives and questions.
The positive form states facts, like who someone is or where something is. In conversation and informal writing, we almost always use contractions (shortened forms). Remember to always use a subject pronoun (I, you, he, she, etc) with the verb.
To make a statement negative, put not after the verb be (am, is, are). You can contract is not to isn't and are not to aren't.
To ask a question, we use inversion: put am, is, or are before the subject.
Positive Short Answers: We don't use contractions in positive short answers (e.g., Yes, I am).
Negative Short Answers: We typically use contractions (e.g., No, I'm not)
W/H questions ask for specific information (like location or identity). The word order is: Question Word/Phrase + Be + Subject.
When using most verbs in English (like work, live, play, study), we follow different rules than the verb 'be'. We use this tense to talk about things that are generally true or for habits and routines.
The key rule is adding -s for the third-person singular (He, She, It).
For I, You, We, and They, use the base form of the verb e.g.I work.
For He, She, and It, add -s e.g.He works.
Some verbs have special spelling rules for the He / She / It form
To ask questions about habits or facts with any verb (except the verb 'be'), we must use the auxiliary verbs do and does.
To form a simple question that can be answered with Yes or No, we use the Auxiliary-Subject-Infinitive (ASI) word order.
Short answers are the quickest way to answer a Do / Does question.
Positive Short Answers: We don't use contractions (e.g., Yes, I do).
Negative Short Answers: We usually use contractions: don't or doesn't (e.g., No, I don't).
For questions that ask for specific information (who, what, where, etc.), we use the QUASI word order: Question Word + Auxiliary + Subject + Infinitive.
Exception: Who / What as the Subject 🕵️ When Who or What acts as the subject of the sentence (the person or thing doing the action), you don't use do or does. The verb follows the rule for He / She / It (it gets the -s ending).
