1. Lesson Overview
In this lesson, you will learn how verb tenses change when direct speech is transformed into reported speech.
When the reporting verb is in the past tense, the verb in the reported clause usually shifts one step back in time. This process is called backshifting.
Example:
Direct speech:
She said, “I am preparing the report.”
Reported speech:
She said that she was preparing the report.
Understanding tense transformations is essential for reporting statements, conversations, and past information accurately.
By the end of this lesson, you will be able to:
-
explain how tense backshifting works
-
apply the full system of tense transformations
-
recognise situations where tense does not change
-
identify and correct errors involving tense shifts
2. Concept Introduction
Consider the following example.
Direct speech:
The researcher said, “The experiment is successful.”
Reported speech:
The researcher said that the experiment was successful.
The present tense is changes to was because the reporting verb said is in the past.
| Direct Speech | Reported Speech |
|---|---|
| is | was |
This backward movement in tense is known as backshifting.
3. Core Explanation
Backshifting occurs when the reporting verb is in the past tense.
Example:
She said that the system was functioning correctly.
The tense moves one step back to reflect that the statement was made earlier in time.
Present → Past
Example:
Direct speech:
She said, “The system works perfectly.”
Reported speech:
She said that the system worked perfectly.
Present Continuous → Past Continuous
Example:
Direct speech:
She said, “The technician is repairing the system.”
Reported speech:
She said that the technician was repairing the system.
Present Perfect → Past Perfect
Example:
Direct speech:
She said, “The report has been completed.”
Reported speech:
She said that the report had been completed.
Past Simple → Past Perfect
Example:
Direct speech:
She said, “The experiment finished earlier.”
Reported speech:
She said that the experiment had finished earlier.
Will → Would
Example:
Direct speech:
She said, “I will submit the report tomorrow.”
Reported speech:
She said that she would submit the report the next day.
4. Rule Table
Tense Backshifting System
| Direct Speech | Reported Speech |
|---|---|
| present simple | past simple |
| present continuous | past continuous |
| present perfect | past perfect |
| past simple | past perfect |
| will | would |
| can | could |
| may | might |
Examples of Backshifting
| Direct Speech | Reported Speech |
|---|---|
| “I work here.” | She said that she worked there. |
| “I am studying.” | She said that she was studying. |
| “I have finished.” | She said that she had finished. |
| “I will travel tomorrow.” | She said that she would travel the next day. |
5. Usage
1. Reporting past conversations
Example:
She said that the experiment was successful.
2. Reporting instructions or statements
Example:
The technician said that the system needed maintenance.
3. Reporting past plans
Example:
She said that she would start the experiment later.
4. Reporting completed actions
Example:
The researcher said that the report had been submitted earlier.
5. Reporting ongoing past actions
Example:
She said that the team was analysing the data.
6. Signal Words
Certain expressions often appear in reported speech involving tense changes.
| Expression | Example |
|---|---|
| earlier | She said that the experiment had finished earlier. |
| before | She said that the report had been completed before the meeting. |
| later | She said that the results would be published later. |
| soon | She said that the system would be repaired soon. |
| already | She said that the data had already been analysed. |
These expressions often appear with perfect or past tense structures.
7. Special Cases
When Tense Does Not Change
Backshifting may not occur if the statement expresses a general truth or universal fact.
Example:
Direct speech:
She said, “Water boils at 100°C.”
Reported speech:
She said that water boils at 100°C.
The tense remains present because the statement is still true.
Reporting with Present Reporting Verb
If the reporting verb is present, tense changes usually do not occur.
Example:
Direct speech:
She says, “I am busy.”
Reported speech:
She says that she is busy.
8. Additional Notes
Backshifting is mainly used when the reporting verb is past.
Example:
He said that the system was working correctly.
However, if the situation is still true, the speaker may keep the original tense.
Example:
He said that the system is working correctly.
Both forms may be acceptable depending on context and meaning.
9. Common Errors
⚠ Not applying backshifting
Incorrect:
She said that she is busy.
Correct:
She said that she was busy.
Explanation:
Present tense usually shifts to past tense.
⚠ Incorrect tense transformation
Incorrect:
She said that she will finish the report.
Correct:
She said that she would finish the report.
Explanation:
Will → would in reported speech.
⚠ Incorrect past perfect usage
Incorrect:
She said that she had finish the report.
Correct:
She said that she had finished the report.
Explanation:
Past perfect requires had + past participle.
⚠ Keeping original tense unnecessarily
Incorrect:
She said that she works there yesterday.
Correct:
She said that she worked there yesterday.
Explanation:
The tense must shift appropriately.
⚠ Incorrect modal transformation
Incorrect:
She said that she can solve the problem.
Correct:
She said that she could solve the problem.
Explanation:
Can → could in reported speech.
