Donno

Donno is a term used in Indian English to mean "I don’t know" or indicate uncertainty. It's derived from regional slang and is often used casually in conversation. Essentially, it’s a way of expressing that you lack information or are unsure about something, similar to saying "I don’t have the answer" or "I’m not sure." The word helps convey uncertainty in a friendly, informal manner, and is understood primarily in Indian English-speaking communities.
