Meaning & readings

mellow, ripen, mature, acquire skill

On’yomi ジュク
Kun’yomi う.れる

Origin

The character combines a sound hint with a fire radical at the bottom. The top component "孰" (pronounced similarly to the character's on'yomi reading) tells you roughly how to say the character, while the fire radical at the bottom indicates the meaning — heat causes food to ripen and cook. Together, the picture is of heat transforming raw ingredients into something mature or fully cooked, which naturally extended to mean becoming skilled or experienced.
