The Tense Comparison Theory in Tagalog Grammar aims to provide guidance on the different ways in which Tagalog expresses time-related information. In Tagalog, the verb affixes play a crucial role in indicating the tense of a verb.

There are three main tenses in Tagalog: present, past, and future. Each tense has its own set of affixes which are attached to the root of the verb to indicate the desired time frame.

The present tense is used to describe actions that are happening at the current moment or habitual actions. The past tense is used to describe actions that have already occurred. The future tense is used to describe actions that will occur in the future.

Tagalog also employs aspect to express different aspects of an action such as completion or ongoingness. The aspect is indicated by the choice of affix used with the verb.

It is essential for learners of Tagalog to understand the Tense Comparison Theory to accurately express time-related information and convey their intended meaning. By mastering this theory, students can effectively communicate about past, present, and future events in Tagalog.
