Let's imagine you are arguing with someone pursuant to an old matter after a short time gap. Some new events make you feel that you will probably hear some new excuses/words from the person you are arguing with. But again he starts talking about the same old words and just repeats the excuses he/she had made before! What would you say here as a disapproval?
— These are all repetitive words/excuses.
— These are all repetitious words/excuses.
Also, I wonder if it would be possible to say:
- Your words / excuses have become repetitive to me.
- Your words / excuses have become repetitious to me.
Based on dictionaries, they both work semantically, but I guess they are not the ways a native would say the same thing.
Repetitive:
- Involvingdoing or saying the same thing several times, especially in a way that is boring:
- A repetitive job/task.
Repetitious:
- Filled with unnecessary and boring things expressed or happening in the same way many times:
- The movie got a little repetitious after the third car chase.
