Indirect adverbial clauses are clauses with a conditional form that do not seem to give conditions, clauses with a temporal form that do not seem to indicate the time etc. For instance, the indirect conditional If you're hungry, there's food in the fridge differs semantically from the direct conditional If you're hungry, I'll give you something to eat. A similar distinction is found in Chinese. This paper examines indirect adverbial clauses in Chinese in light of what we already know about Western languages. In order to show that the patterns described are not simply results of Westernized grammar, the material from modern Chinese is supplied with example sentences from the 18th century novel Hongloumeng.
