Modals of Advice

ការផ្តល់ដំបូន្មាន

We use words like should and ought to to tell someone what is a good idea to do.

យើងប្រើប្រាស់ពាក្យទាំងនេះ ដើម្បីផ្តល់ដំបូន្មាន ឬប្រាប់នរណាម្នាក់ពីអ្វីដែលជាគំនិតល្អគួរធ្វើ។

🧭

Should (Good Idea)

គួរតែ (សម្រាប់គំនិតល្អ ឬរឿងដែលគួរធ្វើ)

Subject + should + base verb

You should sleep early. អ្នកគួរតែគេងឲ្យបានលឿន។

He should study more. គាត់គួរតែខិតខំរៀនបន្ថែមទៀត។

🚫

Shouldn't (Bad Idea)

មិនគួរ (សម្រាប់គំនិតមិនល្អ ឬរឿងមិនគួរធ្វើ)

Subject + shouldn't + base verb

You shouldn't smoke. អ្នកមិនគួរជក់បារីទេ។

She shouldn't eat too much sugar. នាងមិនគួរញ៉ាំស្ករច្រើនពេកទេ។

⚖️

Ought to

គួរតែ (មានន័យដូច should តែផ្លូវការជាងបន្តិច)

Subject + ought to + base verb

You ought to apologize. អ្នកគួរតែសុំទោស។

We ought to help them. ពួកយើងគួរតែជួយពួកគេ។

The "To" Trap! ⚠️

Never use "to" after should!

(កុំប្រើ "to" បន្ទាប់ពីពាក្យ should ឲ្យសោះ! ត្រូវដាក់កិរិយាសព្ទដើមយកតែម្តង។)

You should to go. ❌

You should go. ✔️

Asking for Advice

សុំយោបល់ ឬដំបូន្មាន

Should + Subject + base verb ?

Should I call him? តើខ្ញុំគួរតែតេទៅគាត់ទេ?

What should we do? តើពួកយើងគួរធ្វើអ្វី?

Hi Sokna! In daily conversation, we use "should" much more often. "Ought to" sounds a bit more formal or strong, so you might see it more in writing or important situations! 💡
