platitude

1. N-COUNT A platitude is a statement that is considered meaningless and boring because it has been made many times before in similar situations. 陳詞濫調(diào)[表不滿]

Why couldn't he say something vital and original instead of just spouting the same old platitudes?

他為什么不能說點重要的、有新意的東西，而不只是喋喋不休地講些陳詞濫調(diào)呢？
