Grammar: B1 - ✨ Grammar Essentials: 🧩 Parts of Speech & 🏗️ Sentence Structure - Lesson 9: Conjunctions of Reason & Result (because - review, as, since, so - review)

Reason & Result B1

🔗

Cause & Effect

ហេតុ និងផល (Conjunctions)

We use conjunctions to connect a Reason to a Result.

យើងប្រើប្រាស់ឈ្នាប់ (Conjunctions) ដើម្បីភ្ជាប់ហេតុផល ទៅនឹងលទ្ធផលដែលកើតឡើង។

🤔

The Reason Family

ពាក្យបញ្ជាក់ពី "ហេតុផល" (Why it happens)

Because it rained, I stayed home.

ពីព្រោះតែមេឃភ្លៀង ខ្ញុំបាននៅផ្ទះ។ (Review)

Since it's late, let's go.

ដោយសារតែវាយឺតហើយ តោះទៅ។ (Formal)

She whispered as the baby was sleeping.

នាងបានខ្សឹប ដោយសារតែក្មេងកំពុងគេង។ (Formal)

➡️

The Result Family

ពាក្យបញ្ជាក់ពី "លទ្ធផល" (What happens next)

It rained, so I stayed home.

មេឃភ្លៀង ដូច្នេះខ្ញុំបាននៅផ្ទះ។ (Review)

Reason + SO + Result

"So" is always used to introduce the *effect* of an action.

("So" ប្រើដើម្បីបង្ហាញពីលទ្ធផលនៃសកម្មភាពណាមួយ។)

The Double Linking Trap!

Do NOT use "Because" and "So" in the same sentence!

(ប្រយ័ត្ន! ក្នុងភាសាអង់គ្លេស យើងមិនប្រើ "Because" និង "So" ក្នុងប្រយោគតែមួយនោះទេ។ ជ្រើសរើសយកតែមួយប៉ុណ្ណោះ!)

Because I was tired, so I slept. ❌
Because I was tired, I slept. ✅
I was tired, so I slept. ✅

Teacher, what is the difference between "because", "since", and "as"? Do they mean the exact same thing?

Great question, Sovan! Yes, in this context they all mean the same thing (ហេតុផល). "Because" is the most common. "Since" and "As" are a little bit more formal and are often used at the beginning of a sentence. 📚

I thought "since" was for time, like "since 2010". Can it be used for both?

Excellent observation, Vireak! You are right! "Since" has TWO meanings. It can mean a starting point in time ("I have lived here since 2010") OR it can mean 'because' ("Since it's raining, we will stay inside"). You figure out the meaning from the context of the sentence! 💡
