Verbs: Verb Tenses
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.
Simple tenses
The simple tenses are used for actions that occurred at a specific
time either in the present, past or future, but they do not state
whether or not the action is finished. They are present (simple),
past (simple) and future (simple).
Progressive tenses
The progressive tenses are used to indicate an unfinished action.
They are present progressive, past progressive and future progressive.
Perfect tenses
The perfect tenses describe a finished action. They are present perfect,
past perfect and future perfect.
Perfect progressive tenses
The perfect progressive tenses describe an action that was in progress
but was then finished. They are present perfect progressive, past
perfect progressive and future perfect progressive.
Time Frames + Aspects = Complete Verb Tenses
Complete Verb Tenses: Present
The complete present verb tenses are typically used to describe actions
that are taking place or have taken place repeatedly during the
present time period. The four complete present verb tenses are
Present + (Simple) = Present tense
Present + Progressive = Present progressive tense
Present + Perfect = Present perfect tense
Present + Perfect Progressive = Present perfect progressive tense
