Is there any difference in meaning between "to get someone to do something" and "to get someone doing something"?
If so, when should I use each of them?
Would you please give me a few examples?
I think you already asked this.
To get someone to do something means to get someone to start and complete a task. I got my son to clean his bedroom. I got my assistant to file all the reports.
To get someone doing something means to get someone to start something, or to take up a habit or practice. I got my sister preparing the meal then went in the garden. I got my mother reading the Bible every day.
