register

Read liù, this is colloquial northern speech for a finger ring, always 镏子. The standard word is 戒指. In Taiwan this sense is also pronounced liú.

radical

钅 jīn

metal

钅 is the metal radical, the left-side form of 金. Both senses, gilding with gold and the metallic element, sit naturally under 'metal'.

phonetic

留 liú

to remain; to keep

留 supplies the exact sound liú. Its meaning 'to stay, remain' is incidental here; it works as the phonetic beside the metal radical.
