Explanation of Do and Does
Do and Does are auxiliary verbs in English that are used to form questions and negatives in the present tense and to form questions and negatives in the past tense with “did.”
In the present tense, “do” is used with I, you, we, and they, to form questions and negatives. For example:
- “Do you like pizza?” (question)
- “I do not like pizza.” (negative)
On the other hand, “does” is used with he, she, and it, to form questions and negatives. For example:
- “Does she like pizza?” (question)
- “She does not like pizza.” (negative)
In the past tense, both “do” and “does” are replaced with “did” to form questions and negatives. For example:
- “Did you like pizza?” (question)
- “I did not like pizza.” (negative)
It’s important to note that while “do” and “does” can be used as auxiliary verbs, they can also be used as main verbs with a different meaning. For example:
- “I do my homework every day.” (main verb meaning “carry out”)
- “Do you play the piano?” (main verb meaning “engage in an activity”)
