The present tense is a grammatical tense used to describe actions or states that are currently happening or are generally true. It often conveys habits, routines, or facts. For example, in the sentence "She reads every morning," the verb "reads" is in the present tense, indicating a regular action. In English, the present tense can be simple, continuous, or perfect. The simple present describes habitual actions, while the present continuous indicates ongoing actions, as in "He is running now." The present perfect connects past actions to the present, such as "They have finished their homework."
