临床 (lín chuáng) is a compound word originating from 'at the bedside', used primarily in medical contexts to mean 'clinical' — relating to direct patient care or practical medical work. It almost always appears before nouns, e.g. 临床医生 (clinical doctor) and 临床试验 (clinical trial). Note that although often tagged as a verb in dictionaries, it functions as a noun modifier in modern Chinese.
