Centennial doesn't have grammatical tenses as it is a noun.
Hmmm, another ONE word for past and future? How about, "time."
The word "past" doesn't have a future tense as it's not a verb.
Past and Future. Past: I used to wander through the woods. Future: I can't wait to wander in the woods.
Past
The word "eternity" can be used to describe both the past and the future as encompassing all time.
Past: cried Present: cry Future: will cry
past present
Future tense - will set. Past tense - set.
past - lost present -lose future - will lose
past present and future- time.
It is in the past tense.
It is the past tense.
