🎯 熟练 = 熟 (ripe/cooked) + 练 (drill/practice) — practice until ripe
熟 means ripe or well-cooked, extended to mean familiar or thoroughly known. 练 means to drill or train. Together: so well-drilled it's fully cooked — i.e. skilled and proficient through repetition.
熟 — 享 (offering) + 灬 (fire)
Originally written 孰, depicting hands offering food (享) for cooking. The fire radical 灬 was later added to emphasize cooking with heat. The core sense 'cooked' extended naturally to 'ripe,' 'familiar,' and 'skilled through repeated practice.'
练 — silk radical 纟 + 柬 (select)
练 is a semantic-phonetic compound. The silk radical 纟 gives the meaning, originally referring to boiling raw silk to soften and whiten it. 柬 (jiǎn, 'to select') supplies the sound. From the idea of repeatedly processing silk, the meaning extended to 'practice, train, drill'.
