Origin

The character 鈴 combines the metal radical 金 on the left, which marks it as something made of metal, with 令 on the right, which serves as a sound hint suggesting the pronunciation. Since bells are metal objects that make ringing sounds, the metal component perfectly captures what a bell is made from. The 令 component doesn't contribute to the meaning but helps speakers remember how to pronounce the character, much like how a rhyming word can help you remember a phone number.
