Each verb tense is composed of a time frame (past, present, future) and an aspect (simple, progressive, perfect, perfect progressive). Together, the time frame and the aspect make up the complete verb tense (past progressive, future perfect, etc . . .).
Time Frames
Past, present and future are the three time frames that are used to describe or indicate verb tense. Past tense is used to describe actions that occurred in the past; present tense is used to describe actions that are currently taking place; and future tense is used to describe an action that will take place in the future.
Aspects
Aspect refers to the state of action of a verb. There are four types of verb aspects: simple, progressive, perfect and perfect progressive. See More . . .
