Where & When

សព្វនាមឈ្នាប់បញ្ជាក់ទីកន្លែង និងពេលវេលា

We use Where for places and When for times. They help us connect sentences smoothly.

យើងប្រើ Where ដើម្បីបញ្ជាក់ពីទីកន្លែង និង When សម្រាប់ពេលវេលា។ វាជួយភ្ជាប់ប្រយោគឲ្យមានលំហូរល្អ។

place

place Using "Where"

បញ្ជាក់ពីទីកន្លែង (in/at/on which)

"Where" acts like in which or at which. It tells us the location of the action.

location_city

The city where I grew up is beautiful. ទីក្រុងដែលខ្ញុំបានធំធាត់ឡើង គឺស្រស់ស្អាតណាស់។

restaurant

This is the cafe where we met. នេះគឺជាហាងកាហ្វេដែលពួកយើងបានជួបគ្នា។

calendar_month

calendar_month Using "When"

បញ្ជាក់ពីពេលវេលា (on/in/at which)

"When" acts like on which or in which. It describes a specific time.

event

I remember the day when we first met. ខ្ញុំចាំថ្ងៃដែលពួកយើងជួបគ្នាលើកដំបូង។

history

2020 was the year when everything changed. ២០២០ គឺជាឆ្នាំដែលអ្វីៗគ្រប់យ៉ាងបានផ្លាស់ប្តូរ។

gpp_maybe The Preposition Trap!

Where/When already have the preposition!

(ពាក្យ Where និង When បានរួមបញ្ចូលធ្នាក់ in/at/on រួចស្រេចហើយ ដូច្នេះហាមប្រើវានៅចុងប្រយោគម្តងទៀត!)

The year when I was born in. ❌

The year when I was born. ✅

visibility_off

visibility_off Omitting "When"

ការលុបចោល "When" (កម្រិតខ្ពស់)

In advanced English, we often drop "when" after time words like day, year, or time.

I remember the day [when] we met. ខ្ញុំចាំថ្ងៃដែលពួកយើងជួបគ្នា។

That was the time [when] I cried. នោះគឺជាពេលដែលខ្ញុំបានយំ។

Teacher, can I use "that" instead of "when"? Like "The day that we met".

Hi Panha! Yes, absolutely! "The day that we met" or even "The day we met" (omitting the relative pronoun entirely) are both very common and completely correct in English. Great observation! 🗓️

Can I say "The house where I live in?"

Hi Minea! NO! That's the trap! 😅 Because "where" means "in which", if you say "where I live in", you are actually saying "in which I live in". You must drop the preposition: "The house where I live." 🏠
