Identify the verb tense in the sentence: "He wrote five letters yesterday."

The sentence "He wrote five letters yesterday" uses the past tense, which indicates that the action of writing the letters has already been completed at a specific time in the past—in this case, "yesterday." In English grammar, the past tense is often distinguished by the use of the second form of the verb. Here, "wrote" is the past tense form of the verb "write."

By identifying the time expression "yesterday," it further confirms that the action occurred in the past, reinforcing that this sentence is indeed in the past tense. Understanding the significance of time indicators in relation to verb forms is essential in determining the correct tense.
