Verb "To Be"

កិរិយាសព្ទ To Be (Am, Is, Are)

This is the most important verb in English. It describes identity, location, or feelings.

វាគឺជាកិរិយាសព្ទដែលសំខាន់បំផុតក្នុងភាសាអង់គ្លេស។ ក្នុងភាសាខ្មែរវាប្រែថា គឺ / នៅ / ជា

Positive (+) ➕

ប្រយោគស្រប

Rule: Subject + Be

For "I" am I am a student. (ខ្ញុំគឺជាសិស្ស។)
For "He / She / It" is He is my brother. (គាត់គឺជាបងប្រុសរបស់ខ្ញុំ។)
For "You / We / They" are They are happy. (ពួកគេគឺសប្បាយចិត្ត។)

Negative (-) ➖

ប្រយោគបដិសេធ

For "He / She / It" is not She is not here. (នាងមិននៅទីនេះទេ។)
For "You / We / They" are not We are not ready. (យើងមិនទាន់រួចរាល់ទេ។)

Questions (?) ❓

ប្រយោគសំណួរ

Rule: Swap (ប្តូរទីតាំង) the Subject and the Verb.

For "I" Am I...? Am I late? (តើខ្ញុំយឺតមែនទេ?)
For "He / She / It" Is she...? Is it cold? (តើវាត្រជាក់ទេ?)
For "You / We / They" Are you...? Are you okay? (តើអ្នកមិនអីទេឬ?)

Short Forms ✂️

ទម្រង់កាត់ (ប្រើពេលនិយាយ)

In spoken English, we usually combine the subject and the verb.

I am ➔ I'm I'm a teacher. (ខ្ញុំគឺជាគ្រូបង្រៀន។)
He is ➔ He's He's tall. (គាត់ខ្ពស់។)
They are not ➔ They aren't They aren't here. (ពួកគេមិននៅទីនេះទេ។)
The Missing Verb Trap!

Adjectives need "To Be"!

(ក្នុងភាសាអង់គ្លេស អ្នកមិនអាចដាក់គុណនាមជាប់ជាមួយប្រធានដោយគ្មានកិរិយាសព្ទ To Be ដូចភាសាខ្មែរបានទេ!)
I happy. ❌
(ខុស! ព្រោះអត់មានកិរិយាសព្ទ)
I am happy. ✅
(ត្រូវ! ខ្ញុំសប្បាយចិត្ត។)

Hi Sokha! We use it to describe identity (I am a student), location (He is at home), or feelings/adjectives (They are happy). It links the subject to more information! 🔗

No! "I" is very special and ALWAYS takes "am". So it is always "I am" or "I'm". 🙅‍♂️

Do we use "To Be" with verbs like "run" or "eat"?

Not in the Simple Present! You say "I run", NOT "I am run". We only mix them when we use the "-ing" form (I am running), but we will learn that in the next lesson! 🏃‍♂️
