Tamil grammar is unique and rich, offering an interesting perspective on language structure, especially in terms of tenses. Tense comparison exercises are an integral part of learning Tamil grammar as they provide a solid foundation in understanding verb forms and their use in different contexts. Through these exercises, students learn to distinguish between past, present, and future tenses. Each tense in Tamil has its own set of verb endings and auxiliary verbs, which can further indicate perfect, progressive or habitual aspects of the verbs. Teaching these can be complex, due to the subtleties involved in demonstrating the difference between the tenses.

Moreover, the Tamil language also uses suffixes to denote the person, number, and gender of the subject, so tense exercises should cover these components too. Many exercises involve translating English sentences to Tamil and vice versa. These practices are incredibly beneficial in mastering Tamil tenses and making learners proficient in both written and verbal communication.
