In Nepali grammar, the Tense Comparison Theory refers to the study of the different tenses and their usage. There are four primary tenses in the Nepali language: present tense, past tense, future tense, and imperative tense.

The present tense is used to describe actions happening at the current moment or habitual actions. It is formed by adding specific suffixes to the verb stem.

The past tense is used to indicate actions that have already happened. It is formed by adding specific suffixes to the verb stem.

The future tense is used to express actions that will happen in the future. It is formed by adding specific suffixes to the verb stem.

The imperative tense is used to give commands or instructions. It is formed by removing the verb suffix and adding specific suffixes.

In Nepali grammar, the Tense Comparison Theory emphasizes the importance of using the appropriate tense in different situations. Understanding when to use each tense is crucial for effective communication in the Nepali language. Mastery of the Tense Comparison Theory enables learners to express their thoughts and feelings accurately in various contexts.
