le     modal particle

繁体 traditional:
听 listen: Play audio
语法 grammar: 助词 Particle
笔记 notes: In this use 了 appears at the end of a sentence as a modal particle 语气助词. Use as a modal particle differs from use as an aspectual particle after a verb in that a modal particle indicates the completion of the action for the whole sentence. Sometimes a modal particle is omitted if the sentence contains an aspectual particle and the action of the sentence is simple. There are two common uses: 1. 了 may be used at the end of a sentence to indicate a newly emerged condition (Ho, 2002, '了' 2; Sun 2006, loc. 885). For example, 一切的路都封上了 'All the roads were closed.' (Lao She, 2003, p. 175) 2. 了 may be used at the end of a sentence to indicate a reminder, advice, or urging.
