***NOT A TEACHER***mmasny, good afternoon. I know from your other posts that you are eager to understand English in all its varieties. Here in the United States, people really do say, "I'm beat" to mean they are tired. So I guess we can classify it as "correct." More important, however, is something I think you want to know: Americans often use "beat" instead of "beaten" when they talk about sports and business. For example, the Dodgers (baseball team) was beat last night by...; Come to our store, our prices can't be beat!!! Maybe Americans don't want to use "beaten" in those areas because it would sound as if someone had beaten them with a stick!!! Have a nice day.
