Origin

形声xíngshēngMost characters — around four in five — are built this way: one part hints at the meaning, the other at the pronunciation.
This origin belongs to the traditional form 銨; 铵 is its simplified writing.
The traditional form 銨 pairs 金 (metal) with 安, which gives the sound; the simplified 铵 is a later shorthand.
