Most 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 銳; 锐 is its simplified writing.

The traditional form 銳 pairs 釒, a gold sign, with 兌 as the sound part; the simplified 锐 is a shorthand, so its right side is not the historical sound part.
