Understanding the Past Tense of ‘Will’: Forms, Uses & Examples

by

One of the most fascinating aspects of English grammar is how we express past intentions, promises, or predictions originally made with the modal verb “will.” Mastering how to shift these ideas into the past is crucial for fluent communication, especially when narrating events, reporting speech, or expressing hypothetical scenarios. This involves understanding the past tense form of “will,” which is primarily the modal verb “would.”

“Would” is essential in many advanced grammar structures—such as reported speech, conditionals, polite requests, and expressing future-in-the-past. This knowledge allows speakers and writers to convey complex ideas accurately, add nuance, and create more sophisticated sentence constructions.

This comprehensive guide is designed for English learners at all levels, ESL students, advanced users, teachers, linguists, and anyone aiming to deepen their understanding of English modality and tense. By the end of this article, you’ll be equipped with the skills to recognize, form, and use “would” correctly in various contexts, enhancing both your comprehension and production of English.

3. Definition Section

3.1. What Is the ‘Past Tense of Will’?

The past tense of “will” is primarily expressed by the modal auxiliary verb “would.” Both “will” and “would” are modals, indicating modality such as intention, willingness, or prediction. However, “would” places these ideas into a past or hypothetical context.

Consider that:

  • “Will” is used for future intentions, promises, or predictions.
  • “Would” expresses these same ideas when referring back to the past, or when imagining unreal or hypothetical situations.

3.2. How ‘Would’ Functions as the Past of ‘Will’

“Would” takes on a variety of roles derived from “will,” such as:

  • Reporting past intentions or promises: She said she would help.
  • Expressing polite requests or offers: Would you like some coffee?
  • Indicating hypothetical/unreal situations: If I were you, I would apologize.
  • Describing habitual past actions: When we were kids, we would play outside all day.

3.3. Usage Contexts Overview

“Would” appears in a range of grammatical environments:

  • Direct speech vs. reported speech: shifting from present/future (“will”) to past (“would”)
  • Conditionals: expressing unreal situations or regrets
  • Future-in-the-past: indicating a future event relative to a past moment
  • Polite expressions: softening requests or offers

Habitual past n/a When I was a child, I would visit my grandparents every weekend.
Polite request Will you help me? Would you help me?
Polite offer Will you have some tea? Would you like some tea?

4. Structural Breakdown

4.1. Basic Formation of ‘Would’

As a modal verb, “would” follows the same basic structure as other modals:

  • Modal + base verb: She would go, He would help
  • No “-s” in third-person singular: He would (not “woulds”)
  • Negative form: would not or wouldn’t
  • Question form: Would + subject + base verb?

4.2. Affirmative, Negative, and Interrogative Structures

Here are detailed examples:

  • Affirmative: She would travel every summer.
  • Negative: She wouldn’t travel in winter.
  • Question: Would she travel in winter?

  • said: She said she would call.
  • thought: I thought it would rain.
  • promised: He promised he would help.
  • hoped: They hoped they would finish early.

  • It would be nice to travel.

5. Types or Categories of ‘Past Tense of Will’

5.1. ‘Would’ in Reported Speech

When reporting someone’s statement or thought originally made with “will,” we often backshift “will” to “would” in indirect speech:

  • Direct: “I will help you.”
  • Reported: She said she would help me.

This backshifting indicates the promise or intention was made in the past.

Table 3: Backshifting “Will” to “Would” in Reported Speech
Direct Speech Reported Speech
“I will call you.” He said he would call me.
“They will arrive at 7.” She said they would arrive at 7.
“We will win the game.” They believed they would win the game.
“She will study abroad.” He told me she would study abroad.
“It will rain tomorrow.” I thought it would rain the next day.
“You will like this movie.” She promised I would like the movie.
“I will finish the report.” He said he would finish the report.
“They will help us.” We hoped they would help us.

5.2. ‘Would’ in Conditionals

“Would” is an essential part of conditional sentences:

  • Second Conditional (unreal present/future):
    If I won the lottery, I would travel the world.
  • Third Conditional (unreal past):
    If I had known, I would have called you.
  • Mixed Conditionals: combining unreal past with unreal present/future
    If I had studied harder, I would have a better job now.

5.3. ‘Would’ for Future-in-the-Past

We use “would” to express an action or event that was in the future relative to a point in the past:

  • He knew he would graduate in June.
  • They said they would visit us over the weekend.

This contrasts with using past continuous or “was going to.”

5.4. ‘Would’ as Past Habitual

“Would” can describe repeated or habitual past actions, often alongside time expressions:

  • When we were children, we would play outside until dark.
  • Every Sunday, my grandmother would bake bread.

Note: “Would” is not usually used to describe past states; for those, “used to” is preferred.

5.5. ‘Would’ in Polite Requests or Offers

“Would” has evolved to soften requests and offers, making them more polite or tentative:

  • Would you like some tea?
  • Would you mind opening the window?
  • Would you help me with this?

This usage historically derives from a more indirect, past-oriented form of “will.”

7. Usage Rules

7.1. Backshifting in Reported Speech

Rule: When reporting speech from the past, change “will” to “would” to indicate the statement was made in the past.

Steps:

  1. Identify the reporting verb (e.g., said, told, promised).
  2. Change “will” to “would.”
  3. Adjust time references (e.g., tomorrow → the next day).

Note: Backshifting is optional if the statement is still true or is a universal truth.

7.2. Using ‘Would’ in Conditionals

Second Conditional: If + past simple, + would + base verb.

Third Conditional: If + past perfect, + would have + past participle.

Avoid: Using “would” in the “if” clause.

7.3. Future-in-the-Past Contexts

7.5. Politeness and Softening

“Would” softens requests, suggestions, or offers, making them more polite.
