The past simple tense is a verb tense used to describe an action or event that occurred in the past and has already been completed. It is also called the “simple past tense.”

In English, the past simple tense is formed by adding “-ed” to regular verbs, while irregular verbs have a unique past simple form. For example:

– Regular verb: “walk” becomes “walked”
– Irregular verb: “go” becomes “went”

The past simple tense is often used to describe a completed action that happened at a specific time in the past. For example:

– “I ate breakfast at 8am this morning.”
– “He watched a movie last night.”

It can also be used to describe a habitual action in the past. For example:

– “She always walked to school when she was young.”
– “They usually played tennis on weekends.”

In addition, the past simple tense can be used to describe a past event that occurred over a period of time. For example:

– “I lived in New York City for five years.”
– “They worked together for a decade.”
