• Seeing is believing.
- Here, ‘believing’ is- Gerund as a complement of a verb.

- উল্লিখিত বাক্যে 'believing' - verb (is) এর Object হিসেবে বসে subject complement রূপে কাজ করেছে, তাই এটি Gerund.
- এখানে Linking verb (is) -এর complement হিসেবে Gerund হয়েছে।
- অর্থাৎ,এখানে Seeing -ই হচ্ছে believing (believing renaming the subject "Seeing").
- এটি subject 'Seeing' কে modify করছে না, তাই এটি Participle হবে না।

• Gerund:
- Verb -এর সাথে ing যোগ হয়ে যদি noun -এর কাজ করে অর্থাৎ, একই সাথে Verb ও noun -এর কাজ করে, তখন তাকে Gerund বলে।
- সহজে → Gerund = Verb + ing = noun = Verb + noun -এর কাজ করে।
- Gerunds don’t describe action—they act as nouns.

• Functions of the Gerund:
1. As a subject of a verb: Rising early is a good habit.
2. As an object of a verb: I like reading poetry.
3. As an object of a preposition: I am tired of waiting.
4. As a complement of a verb: Seeing is believing.
