What is the verb tense of the sentence 'They walked home from school today'?

The verb tense of the sentence "They walked home from school today" is in the past tense. This is identified by the verb "walked," which indicates that the action took place in a time that has already occurred, specifically earlier in the day when the subject, "they," completed the act of walking home from school.

In English, past tense is used to describe actions or events that have already happened. This is evident in the structure of the verb where the base form "walk" has been modified with the "-ed" ending to create "walked," signaling that the action is not occurring now (present) or will occur later (future) but has already been completed.

Recognizing the distinction between past tense and other forms is crucial. The present tense describes actions happening now, future tense refers to actions yet to happen, and present perfect indicates actions that have been completed at some point in the past but are relevant to the present moment. Each tense serves different purposes in conveying when actions occur, and understanding this helps in forming grammatically correct sentences.
