What you’ll learn

Use participial modifiers after nouns.

កាត់ relative clause ដោយរក្សាន័យត្រឹមត្រូវ។

Meaning and use

Relative clauses can sometimes become shorter noun modifiers: people waiting outside and documents signed yesterday. An -ing modifier often has an active meaning; a past participle modifier often has a passive meaning. Reduction must preserve meaning; a simple -ing form cannot reliably retain every tense or modal distinction.

Relative clause ខ្លះអាចកាត់ជា -ing ឬ past participle ក្រោយនាម។ People waiting មានន័យ active; documents signed មានន័យ passive។ មិនមែនគ្រប់ឃ្លាអាចកាត់ដោយរក្សាន័យដដែលទេ។

Common mistakes

Instead of	Use	Why
The students waited outside are tired. (intended: currently waiting)	The students waiting outside are tired.	Use the active -ing modifier for those waiting.
The form signing by Maly is here.	The form signed by Maly is here.	The form receives the action, so use a past participle.
