Verb tenses refer to the different forms that a verb can take to indicate the time of an action or event. There are three main verb tenses in English: past, present, and future. Each tense has different forms and is used to convey different meanings.
1. Past tense: This tense is used to talk about actions or events that have already happened. It is formed by adding "-ed" to regular verbs or using irregular verb forms. For example: "I walked to the store yesterday."
2. Present tense: This tense is used to talk about actions or events that are happening now or are generally true. It is formed by using the base form of the verb. For example: "She reads a book every night."
3. Future tense: This tense is used to talk about actions or events that will happen in the future. It is formed by using "will" or "shall" before the base form of the verb. For example: "They will go to the party tomorrow."
In addition to these basic tenses, there are also other verb forms that indicate different aspects of time, such as the present continuous tense (e.g., "I am eating dinner") and the past perfect tense (e.g., "She had already left when I arrived").
