Conditional Sentences 

If I have time, I will go. I would help you, if I were a king এখানে লক্ষণীয় প্রতিটি বাক্যেই একটি করে শর্ত বা condition   প্রকাশ পাচ্ছে। আর এমনি ভাবে কোন বাক্যে কোন শর্ত বা condition প্রকাশ পেলে তাকে conditional Sentence বলে।

N.B. Conditional Sentence এ ২ টি অংশ থাকে ‘If’দিয়ে যুক্ত অংশ কে .If clause বলে এবং অপর অংশ কে Main clause বলে। If clause টি বাক্যের শুরুতেও হতে পারে আবার শেষেও হতে পারে। উপরের Example লক্ষ্য কর।
