It is often very confusing for humans to speak about events that happened in a future or past that will now never be because of someone's time-travelling activities. Here are the proper words to use when speaking in these tenses:
Future Events That Will Now Not HappenEdit
If a change in the space-time continuum (S-T.C.) results in a future event that happened in the original timeline ceasing to be going to happen, that event won't happen (an alternate dialect of this is won't). If that future would-have-happened is not likely to be going-to-happen, then that event can't happen.
Example: "I won't have five kids and my husband can't marry me because he was killed by time police when he was five."
Future Events That Will Now HappenEdit
If a change in the S-T.C. means that an event that wouldn't have happened will now happen in the future, that event is a changed-future-event (a C.F.E.) that will happen. No special tenses are required for events that are part of the current timeline.
Example: "I will never marry because my husband was killed when he was five."
Past Events That Would Have HappenedEdit
If a change in the S-T.C. means that what would have been a past event has been changed and didn't happen, then that event didn't happen, or didn't happen, and hasn't happened.
Ex: "I didn't have any children because the Time Police killed my husband"
Past Events That Did HappenEdit
If a change in the S-T.C. means that a past event that didn't happen, now has happened, that is a changed-past-event (a CPE). No special tenses are required for events that are part of the current timeline.
Ex: "I don't have any children because my husband died."
Circumstances That Would Have Been TrueEdit
If something would have been true except that the S-T.C. was distorted, then it isn't the case, doesn't work, or isn't the case (see Quick Rules).
Ex: "My husband doesn't exist because he was killed."
Circumstances That Now Are TrueEdit
If a change in the S-T.C. means that a current circumstance is now in place that would not have been true without the change, then that is a changed-current-circumstance (a CCC). No special tenses are required for circumstances that are part of the current timeline.
Ex: "I don't have a husband."
The general rule of time travel tenses (if you don't have time to look up the tenses but want to convey that you are speaking in a TTT) is to add an "i" in the word after the vowel that appears in the current timeline tense (CTT). The number of times that an event was changed back and forth from happening/happened to not happening/not happened can be determined from the number of "i"s that are added to the word. If an event willn't happen, but it was changed back to not-going-to-happen three times, then it wiiilln't happen (These special distinctions can only be observed when written down or the vowel is held when saying the word).
If a CTT word already has an "i" as the vowel, add an "a" in front of the "i". To denote a number of timestream alterations, add "i"'s as normal.
isn't = aisn't
didn't = daidn't
