In Persian Grammar, the Tense Comparison Theory helps us understand the nuances of verb tenses and their usage. Persian has several tenses, including past, present, and future, each with their own peculiarities.

The Tense Comparison Theory allows us to compare and contrast the usages of different tenses in Persian. For example, it helps us differentiate between the past simple and past continuous tenses. The past simple tense is used to express completed actions in the past, while the past continuous tense is used to describe ongoing actions in the past.

The theory also helps us understand the differences between the present simple and present continuous tenses. The present simple tense is used to express general truths, habits, and routines, while the present continuous tense is used to describe actions happening at the moment of speaking.

Furthermore, the Tense Comparison Theory allows us to analyze the differences between future tenses. It helps us understand the distinctions between the future simple, future continuous, and future perfect tenses.

Overall, the Tense Comparison Theory is a valuable tool in Persian Grammar that helps students grasp the intricacies of verb tenses and their appropriate usage.
