When we say “I have absolutely no idea“, it means that the person doesn’t know something or is entirely unsure about a situation. It’s a very clear way of saying “I don’t know”. It’s used when the person is not able to answer a question or when they’re completely clueless about a situation.
Here are two examples in sentences:
Example 1:
When asked about the answer to the difficult math problem, John said, “I have absolutely no idea“.
Example 2:
Emma looked at the pile of disassembled furniture parts and admitted, “I have absolutely no idea” how to put it together.
Now, let’s see two examples in a conversation:
Example 3:
Mike: What do you think the weather will be like tomorrow?
Anna: I have absolutely no idea, Mike. I haven’t checked the forecast yet.
Example 4:
Sarah: Do you know when the next bus is coming?
Tom: Sorry, Sarah, I have absolutely no idea. I forgot to check the timetable.
So, when someone says “I have absolutely no idea“, they’re clearly stating that they don’t know something or are unsure about a situation. It’s a way to express that you lack knowledge about something specific.
