Future in the past: the four forms
Sometimes a story looks forward from a moment in the past. A promise made on Monday concerned Tuesday, which was still in the future then. These four combinations extend the familiar tense chart with a past viewpoint.
START WITH A MOMENT
On Monday, Maya said, “I will call you on Tuesday.” You report it later.
Maya said she would call me on Tuesday.The call was future relative to the moment Maya spoke. The sentence alone does not tell us whether she actually called.
This diagram marks the order of past reference points only. A reported future occurs after the original statement; relative to now, it may be past, present or future.
PUT IT TOGETHER
The form, made simple.
| Form | Structure & example |
|---|---|
| Simple | would + base verbShe said she would call. |
| Continuous | would be + verb-ingShe said she would be working at six. |
| Perfect | would have + past participleShe said she would have finished by six. |
| Perfect continuous | would have been + verb-ingShe said she would have been working for eight hours by six. |
KNOW WHEN TO USE IT
Here is where it fits.
01A future viewed from an earlier moment
The reference point is the time of the original statement. Would replaces will in a common backshift pattern. Reported speech also changes pronouns and time expressions when the new context requires it; the next day may replace tomorrow. Backshift is not always required if the information remains current.
On Monday, he said he would send the file the next day.
02Preserve the original viewpoint
Would be working preserves the sense of an activity in progress. Would have finished preserves completion before a deadline. Would have been working preserves duration up to a future checkpoint. The last form is uncommon in everyday conversation, but understandable when the context makes all the time relationships clear.
03Not every would is future in the past
Would can also express a hypothetical result, a polite request or a repeated past activity. I would travel if I had time is hypothetical. Would you help me? is a request. Identify the reporting context before classifying the form.
She said she would have finished by six. / She would have finished if the power had not failed.
04Was going to and plans that changed
Was/were going to describes an intention or expectation held in the past. It can introduce a plan that changed, but it does not by itself prove the plan was cancelled. Add the outcome if that information matters.
I was going to walk, but it started raining, so I took a taxi.
05Why some charts show 12 and others 16
Many teaching charts group present, past and future reference with simple, continuous, perfect and perfect continuous aspect: twelve combinations. Adding future in the past gives sixteen. This is a learning framework; many grammatical descriptions recognize only present and past as inflected English tenses. Learn the meanings rather than treating the count as a test of correctness.
SMALL CHANGES, CLEARER ENGLISH
A few things to watch.
Would takes the base verb, just like will.
