1. 闲扯；空谈；喋喋不休
If you say that someone prattles on about something, you are criticizing them because they are talking a great deal without saying anything important.
e.g. Lou prattled on about various trivialities till I wanted to scream...
卢就各种芝麻小事唠叨个没完，后来我烦得都想尖叫了。
e.g. She prattled on as she drove out to the Highway...
她开车上公路时一直说个没完。
