副词修饰动词、形容词和其他副词等，用来说明时间、地点、程度、方式、频率等，如：often, here, very, quickly, always等。除本身就是副词的，如now现在、there那里、rather非常，部分副词是由形容词加词尾-ly转换来的，如firmly坚决地，happily幸福地，也有部分副词与形容词同形，如straight adj．直率的，straight adv．坦率地；enough adj．充足的，enough adv．充足地；long adj．长的，长久的；long adv．长久地。副词可分为普通副词（如together, well, seriously, slowly, carefully）、疑问副词（如when, where, how, why）、关系副词（where, when）与连接副词（如then, so, therefore, however, hence, thus, nevertheless, otherwise, still）。

副词在句中可用作状语、表语等，最主要的功能是作状语，如：
