Reported Speech

ការនិយាយរាយការណ៍ និងការថយអតីតកាល (Backshifting)

When we report what someone said in the past (e.g., "He said..."), we must move the verb tense one step back into the past.

Direct Speech ➜ Reported Speech

នៅពេលដែលយើងរាយការណ៍ពីអ្វីដែលគេនិយាយក្នុងអតីតកាល កិរិយាសព្ទត្រូវតែថយទៅរកអតីតកាលមួយកម្រិត។

🕰️

Tense Shifters 🕰️

ការផ្លាស់ប្តូរកាល (Present ➜ Past)

Present Simple ➜ Past Simple "I am happy." He said he was happy. (គាត់បាននិយាយថា គាត់សប្បាយចិត្ត។)

Present Cont. ➜ Past Cont. "I am playing." She said she was playing. (នាងបាននិយាយថា នាងកំពុងលេង។)

Past Simple ➜ Past Perfect "I went home." He said he had gone home. (គាត់បាននិយាយថា គាត់បានទៅផ្ទះរួចហើយ។)

🔄

The Modals 🔄

កិរិយាសព្ទជំនួយ (Can/Will/Must)

Modals also take a step back in time when reported.

Will ➜ Would "I will call you." She said she would call me. (នាងបាននិយាយថា នាងនឹងទូរស័ព្ទមកខ្ញុំ។)

Can ➜ Could "I can swim." He said he could swim. (គាត់បាននិយាយថា គាត់អាចហែលទឹកបាន។)

Must ➜ Had to "I must go." She said she had to go. (នាងបាននិយាយថា នាងត្រូវតែទៅ។)

📍

Time & Place 📍

ការផ្លាស់ប្តូរពេលវេលា និងទីកន្លែង

Since we are reporting from a different time or place, these words must change too.

Here ➜ There "I live here." He said he lived there.

Today ➜ That day "I am busy today." She said she was busy that day.

Tomorrow ➜ The next day "I will go tomorrow." He said he would go the next day.

The General Truth Trap!

Do NOT backshift universal facts!

(ប្រសិនបើអ្វីដែលគេនិយាយគឺជាការពិតជាសកល ឬការពិតទូទៅដែលមិនប្រែប្រួល អ្នកមិនចាំបាច់ថយកាលទៅអតីតកាលទេ!)

"The earth is round." He said the earth was round. ❌
(It didn't stop being round!)

"The earth is round." He said the earth is round. ✅
(Keep it in the present tense.)

Quick Check ⚡

ការត្រួតពិនិត្យរហ័ស

Present to Past

Direct: "I want pizza."

Reported: He said he ___ pizza.

(គាត់និយាយថា គាត់ចង់ញ៉ាំភីហ្សា។)

Modal Shift

Direct: "I will be late."

Reported: She said she ___ be late.

(នាងនិយាយថា នាងនឹងមកយឺត។)

Time Shift

Direct: "I saw him yesterday."

Reported: She said she had seen him ___.

(នាងបាននិយាយថា នាងបានឃើញគាត់កាលពីម្សិលមិញ។)

Modal Shift

Direct: "I can swim."

Reported: He said he ___ swim.

(គាត់បាននិយាយថា គាត់អាចហែលទឹកបាន។)

THE TRAP! ❌

Direct: "Water boils at 100 degrees."

Reported: The teacher said water ___ at 100 degrees.

(តើការពិតជាសកល គួរតែថយអតីតកាលដែរឬទេ?)

Do I ALWAYS have to backshift the tense?

Not always! If the reporting verb is in the present (e.g., "He SAYS..."), you don't backshift. Also, if the statement is still true right now (like a general fact), you don't have to backshift. But if the reporting verb is "He SAID...", you usually must take one step back in time! ⏳

What happens if the direct speech is already in Past Perfect? Like "I had finished."

Great question! The Past Perfect tense is the furthest back in time you can go in English grammar. So, it just stays the same! "I had finished" ➜ She said she had finished. No change! 🛑

Does "this" change to "that"?

Yes, absolutely! Because the speaker is reporting the story from a distance, "this" becomes "that", and "these" becomes "those". For example: "I like this book" ➜ He said he liked that book. 📖
