Grammar & Usage

How it works

This is a verb phrase structured as 'verb + 了 + numeral-classifier phrase + noun'. '引发' (yǐnfā) is the verb meaning 'to spark' or 'to trigger'. '了' (le) indicates completion or actualization of the action. '一系列' (yī xìliè) means 'a series of', acting as a numerical classifier phrase for the noun '问题' (wèntí), which means 'problems'. The structure describes the action of causing a chain of issues.
