• He is tired of waiting for the bus every day. The underlined part is an example of - Gerund.
- "Waiting" is a gerund because it is the -ing form of a verb (wait) that functions as a noun.
- After a preposition (of), a verb must be in the gerund form (verb + ing) rather than the infinitive.
- বাক্যে verb + ing যুক্ত word যদি বাক্যের preposition এর পরে object হিসেবে বসে, তবে তা সাধারণত Gerund হবে।
- এখানে "waiting" একটি gerund, কারণ এটি verb + ing এবং noun হিসেবে ব্যবহার হয়েছে।

• Gerund:
- Verb এর সাথে ing যোগ হয়ে যদি noun এর কাজ করে অর্থাৎ Verb ও noun এর কাজ করে, তাহলে তাকে Gerund বলে।
- সংক্ষেপে: Gerund = Verb + ing = noun = Verb + noun.
- It is a word ending in "-ing" that is made from a verb and used like a noun.
