熟练 (shú liàn) is an adjective meaning 'skilled' or 'proficient' — describing someone who has practiced a task so thoroughly that they perform it smoothly and confidently. The character 熟 means 'familiar' or 'well-known', often implying deep knowledge through repeated exposure, while 练 means 'to practice' or 'to train'. Together, they convey the idea of competence gained through consistent, deliberate practice — not just theoretical understanding, but practical mastery.

This word is commonly used to describe abilities in work, study, sports, arts, or daily life — such as typing, cooking, driving, or speaking a language. It’s neutral in register and appropriate in both formal and informal contexts. Unlike some synonyms, 熟练 emphasizes observable fluency and reliability rather than innate talent or speed alone. It frequently appears after the subject and before verbs (e.g., 他操作电脑很熟练), or in predicate position with 是…的 structures (e.g., 他是熟练的程序员).
