English constantly engineers new vocabulary by combining existing words through compounding, blending, and using acronyms.

Before vs. After the Noun

(ក្បួនប្រើសញ្ញាភ្ជាប់ (-) ក្នុងគុណនាមបន្សំ។ តើយើងគួរប្រើវានៅពេលណា?)

BEFORE the noun: USE Hyphen

When the compound adjective comes directly before the noun it modifies.

He is a well-known actor.

AFTER the noun: NO Hyphen

When the compound adjective follows a linking verb (like 'is' or 'are').

That actor is well known.

Teacher, do I *always* need a hyphen for compound adjectives? It's so confusing.

Hi Piseth! Great question. The general rule is: ONLY use the hyphen when the compound adjective comes *before* the noun it describes.

Example: "A brightly-lit room" (hyphen because it's before 'room'). BUT "The room is brightly lit" (no hyphen because it's after the verb 'is'). Keep practicing! 📝
