Learn to guess meanings using Context and Word Parts.

កុំពឹងផ្អែកលើវចនានុក្រមរហូត! ត្រូវរៀនទាយអត្ថន័យតាមរយៈបរិបទ និងរចនាសម្ព័ន្ធពាក្យ។

🔎 Context Clues

ទាយតាមរយៈពាក្យជុំវិញ (បរិបទ)

Look at the other words in the sentence. They often contain synonyms or explanations.

"He hadn't eaten anything for two days; he was absolutely famished."

The Clue: "hadn't eaten for two days"
The Guess: Famished must mean very hungry!
(មិនបានញ៉ាំអី២ថ្ងៃ ដូច្នេះ famished ប្រាកដជាមានន័យថា ឃ្លានខ្លាំង!)

🧩 Prefixes (Start)

បុព្វបទ (ពាក្យបន្ថែមខាងមុខ) ផ្លាស់ប្តូរអត្ថន័យ

Prefixes change the meaning of a word. E.g., un- (not), re- (again), mis- (wrong).

mis + understand

misunderstand

= To understand wrongly.

(យល់ខុស)

🧩 Suffixes (End)

បច្ច័យ (ពាក្យបន្ថែមខាងក្រោយ) ប្តូរថ្នាក់ពាក្យ

Suffixes usually change the grammar (Noun to Adjective). E.g., -less (without), -ful (full of).

harm + less

harmless

= Without harm (safe).

(គ្មានគ្រោះថ្នាក់)

🌱 Root Words

ឫសគល់នៃពាក្យ (អត្ថន័យគោល)

The root gives the core meaning. If you know the root, you can guess many words!

PORT

(Latin root meaning "to carry")

export = carry out

import = carry in

transport = carry across

The False Friend Trap!

Beware of "Invaluable"!

Normally, in- means "not" (e.g., incorrect = not correct). But invaluable is an exception!

Invaluable = Not valuable ❌

Invaluable = EXTREMELY valuable ✔️

(មានតម្លៃមិនអាចកាត់ថ្លៃបាន!)
