1 What Are One-Word Substitutions?

A one-word substitution replaces a longer descriptive phrase with a single word. For example, instead of saying “a person who looks on the bright side,” you use “optimist.” This makes your writing or speech concise and powerful.


এক কথায় প্রকাশ হলো এমন একটি শব্দ, যা একটি দীর্ঘ বাক্য বা বাক্যাংশকে সংক্ষিপ্ত করে প্রকাশ করে। যেমন: “একজন ব্যক্তি যে সবকিছুতে ভালো দিক খোঁজে” — এই বাক্যটি আমরা একটি মাত্র শব্দ দিয়ে লিখতে পারি: “Optimist” (আশাবাদী)।


এর ফলে আপনার লেখনী এবং কথাবার্তা হয় সংক্ষিপ্ত, পরিষ্কার, এবং প্রভাবশালী।
