Nominalization with '-a' (-আ) suffix

Grammar Rule in 30 Seconds

Turn any verb into a noun by adding '-a' to the root, creating a concept or action name.

  • Add '-a' to the verb root: 'kora' (to do) becomes 'kora' (the act of doing).
  • Use it as a subject or object: 'kora bhalo' (doing is good).
  • It functions exactly like a noun in a sentence structure.
Verb Root + 'a' = Noun (Action)

Meanings

The '-a' suffix transforms a verbal root into a gerund or verbal noun, representing the action itself as a concept.

1

Gerundial Noun

Representing the act of doing something.

“খাওয়া শেষ হয়েছে।”

“গান গাওয়া আমার শখ।”

2

Abstract Concept

Turning a verb into a state or concept.

“হাঁটা ভালো ব্যায়াম।”
