Time & Space

ឃ្លាអនុប្រយោគបញ្ជាក់ពេលវេលា និងទីកន្លែង

Relative clauses with "where" and "when" connect sentences by referring back to a specific place or time.

យើងប្រើ "where" (ទីកន្លែង) និង "when" (ពេលវេលា) ដើម្បីភ្ជាប់ប្រយោគពីរចូលគ្នា ជៀសវាងការសរសេរច្រំដែល។
📍

Places: "Where" 📍

ការប្រើប្រាស់សម្រាប់ទីកន្លែង
Instead of two sentences:
"This is the cafe. We met here."
Place + where + Subject + Verb
This is the cafe where we met. នេះគឺជាហាងកាហ្វេដែលពួកយើងបានជួបគ្នា។

Times: "When" ⏳

ការប្រើប្រាស់សម្រាប់ពេលវេលា
Instead of two sentences:
"I remember the day. We met then."
Time word + when + Subject + Verb
I remember the day when we met. ខ្ញុំចងចាំថ្ងៃដែលពួកយើងបានជួបគ្នា។
The Grammar Trap! ⚠️

Where vs. Which

(កុំច្រឡំប្រើពាក្យ "Where" គ្រប់ពេលដែលនិយាយពីទីកន្លែង! វាអាស្រ័យលើសកម្មភាពក្នុងប្រយោគ។)
Use "WHERE" (Action happens IN the place)
"The house where I grew up." (I grew up IN the house)
Use "WHICH" (The place IS the object/subject)
"The house which has a red door." (Not 'where' because there's no 'in/at' action happening)

Formal Expansion 👔

ការប្រើប្រាស់កម្រិតខ្ពស់ / ផ្លូវការ

In formal or written English, we often replace where and when with a Preposition + Which.

Where = In/At which "The building in which he works." អគារដែលគាត់ធ្វើការ។ (ផ្លូវការជាង "where he works")
When = On/In which "The day on which she arrived." ថ្ងៃដែលនាងបានមកដល់។ (ផ្លូវការជាង "when she arrived")

"This is the restaurant ___ serves the best pizza."
(នេះជាភោជនីយដ្ឋានដែលមានភីហ្សាឆ្ងាញ់ជាងគេ។)
(Hint: The restaurant is the *subject* of "serves", so we can't use 'where'.)

Teacher, can I just use "that" instead of "where"? Like "The city that I live"?

Hi Sovan! Be careful! You CANNOT say "The city that I live." You must say "The city WHERE I live" OR "The city that I live IN." You need that preposition if you use 'that' or 'which'! 🧠💡

Do we need to use commas for these clauses?

Usually, no! These are "defining" relative clauses, meaning they are essential to the sentence. Only use commas if it's extra info about a specific, named place (e.g., "Paris, where I live, is beautiful.") ✍️
