Makes a harsh, metallic ringing sound; a sharp or discordant noise.
From Middle English 'jangle,' possibly from Old French 'jangler' (to babble, chatter). The sound-meaning evolved from talking/chattering to producing harsh metallic sounds.
The word 'jangle' is itself an onomatopoeia—say it aloud and you can hear the discordant metallic sound it describes, which is why it's perfect for describing jangling keys or nerves.
