TEAS-focused breakdown of Tense, with a deep dive into the Present Tense
Part 1: What is "Tense"
in Grammar?
Definition:
In grammar, Tense
is a verb form that shows the time of an action, event, or condition relative
to the moment of speaking or writing.
Tense tells you when
something happens.
In English, there are three
main time periods: Past, Present, and Future.
Each of these has four
aspects: Simple, Continuous (Progressive), Perfect, and Perfect
Continuous.
This gives us a total of 12 tenses.
