Meaning at a glance

  • Primary sense: A percussion instrument that makes a clacking noise.
  • Grammar: clacker is listed as noun, slang.
  • Nearest alternatives: anus, boiler factory, boiler room, bull-roarer.
  • Usage evidence: The last leg of one of our runs was Valencia to Madrid, a straight-line distance of about 93 nautical miles. A competition developed as to who could fly it in the least amount of time. For a couple of weeks, I held the record at 24 minutes, but then another captain did it in 23. One captain claimed he had done it in 22, but his flight engineer let it be known that the overspeed warning clacker had sounded during the flight. You could fly the leg however you wished, but if the overspeed warning—a distinctive loud clacking sound—went off, the run didn't count.

Definition decision workflow

Check whether "clacker" is acting as noun, slang in your sentence. A definition is only useful when the grammar matches the way the word is being used.

2. Test the nearest option

3. Confirm with context

Use the example sentence below as an evidence check, then read your own sentence out loud to catch tone or rhythm problems.

Review note: Definition pages are checked for source coverage, sentence evidence, synonym support, and editorial insight before they are treated as approval-ready pages. If the evidence is too thin, the page remains available to users but is kept out of the approval-facing indexed inventory.

Final meaning check

Before publishing a sentence with "clacker", ask whether the word helps the reader understand the idea faster. A precise word should reduce confusion, not simply make the sentence look more polished.
