If there is a question word (where, what, how, who etc.), we put it at the beginning of the sentence.
What are you cooking?To give a short answer, we only keep the auxiliary verb am/is/are (+ not) and do not repeat the main verb.
Examples Am I working hard now? Yes, I am. Are you going home? Yes, you are. Is he leaving? No, he isn't. Is she wearing a hat? Yes, she is. Is it snowing outside? No, it isn't. Are we having fun? Yes, we are. Are they having lunch? No, they aren't.
Pay attention In "yes" answers, we do not shorten the auxiliary verb: Yes, I am. Yes, you are. Yes, he is. In "no" answers, it is better to shorten it: No, I 'm not. No, you aren't. No, he isn't.
| Yes, | I | am. | No, | I'm not. | or | No, | he isn't. she isn't. it isn't. |
| he she it | is. | he's not. she's not. it's not. | |||||
| we you they | are. | we're not. you're not. they're not. | we aren't. you aren't. they aren't. |
