The sequence of tenses is when the tense of the subordinate verb changes based on the tense of the main verb in a sentence with two clauses. The tense of the subordinate clause should be modified accordingly to maintain a relative coherence of time. 

The sequence of tenses in English grammar is a rule that dictates how tenses should be used when forming sentences. The law of sequence of tenses states that when a sentence includes a verb in the past tense, all verbs that follow must also be in the past tense. 

The sequence of tense implies that when two clauses make up a sentence, the tense of the subordinate verb is changed according to the tense of the main verb. This means that the tense of the subordinate clause should be modified accordingly to ensure a relative coherence of time. 

Here are some tenses:
Past tense: Expresses actions that have happened in the past.
Present tense: Used to show that something is happening in the present moment.
Future tense: When the principal clause is in the future tense, the subordinating clause should not be in the future tense. Instead, the subordinating clause should begin with words like when, until, before, or after. For example, "I will call you when dinner is ready".
Present perfect tense: Refers to actions that have already occurred but have their effect at the moment.
Present continuous tense: Indicates that an action or condition is happening now, frequently, and may continue into the future.
Past perfect tense: Used to sequence past events. To use this tense, add a "had" + the simple past tense of a verb.
Future Continous tense: When applying the sequence of tense rules, the speaking or the thinking or the believing must occur in the past. For example, "he says that she will come".
