What does 'does that ring a bell' mean?

What it means: To sound familiar - like something you've encountered before but perhaps can't remember clearly. "Does that ring a bell?" = "Does that sound familiar to you?"

Where it comes from: A bell produces a clear, recognisable sound. When something "rings a bell," it triggers a recognition response - like a signal in the brain saying "I know this."

• "Does the name Sarah Holden ring a bell?"
• "I can't place it - it rings a bell but I can't remember where from."
• "That address rings a bell - I think I've been there."

The opposite: "It doesn't ring a bell" = "I don't recognise that at all."

• "Sound familiar?" - the plain question version
• "I've heard that name before..." - partial recognition
• "That's ringing a bell" - present progressive, mid-recognition
• "I can't place it" - recognition without recall
