Here's why the concept of a "comparative form of tense" doesn't work:
* Tense is categorical: Tenses are distinct categories like past, present, and future. You can't compare them as you would adjectives (e.g., "bigger," "smaller").
* Comparison is for adjectives and adverbs: Comparative forms are used to compare qualities or degrees (e.g., "stronger," "faster"). Tenses describe time, not qualities.
Instead of "comparative form of tense," you might be thinking about:
* Sequence of tenses: This refers to how tenses relate to each other within a sentence, particularly in subordinate clauses. For example, "I knew she was coming" (past perfect tense in the main clause, past continuous in the subordinate clause).
* Verb aspect: This refers to how an action is viewed in time (e.g., completed, ongoing, habitual). Aspect can be compared to some degree, like "I was walking" (ongoing) versus "I walked" (completed).
To accurately express your meaning, consider rephrasing your question. For example, you could ask:
* How do I express a sequence of tenses in a sentence?
* What is the difference between verb aspect and tense?
* Can I compare the duration of actions in different tenses?
