繁体 traditional:
听 listen: Play audio
语法 grammar: 助词 Particle
笔记 notes: In this usage 了 is an aspectual particle 动态助词. Here 了 is placed after the verb and before its object to indicate that an action has been completed (Li Shaoqi, 2003, pp. 430-431; Ho, 2002, '了' 1). For example, 他似乎明白了点 'he seemed to understand something.' (Lao She, 2003, p. 218) In this example the verb is 明白 'understand' and the object is 点 '[a little] something.' 了 cannot be used for non-action verbs, such as 喜欢, 是, 像. If there are two verbs in series then 了 should be placed after the second verb. 了 is the third most frequent word in the Beijing Language Institute's 1985 frequency wordlist (Ho, 2002, '了').
