- Do not confuse with 'клаксон' (klakson) - a direct borrowing with the same meaning, so it's a cognate. No trap, but note the spelling difference.
Common Mistakes
- Confusing it with a generic 'alarm' (a klaxon is a specific type). Incorrect spelling: 'claxon' is a common variant but 'klaxon' is standard.
- Using it as a verb without context (it's primarily a noun).
