Bo: What did you do last weekend?
Abe: I backed to my hometown.
Let's look at Abe's answer because it doesn't make sense. What is the verb in the sentence? "Back." When we use "back" as a verb, it means to support or endorse. For example:
Newspapers in the U.S. always choose to support a presidential candidate a few days before the election. Last year, The New York Times backed Barack Obama while The New York Post backed John McCain.
You can also use "back" at the racetrack for the horse you gambled on.
I backed the wrong horse in the last race and lost $100.
So, what should Abe have said?
Abe: I went back to my hometown.
go back = return
back up (driving) - During the driving test, you have to show the proper way to back up while parking.
A while back, my co-workers and I got into a conversation about what specific things turned each of us on. Yes, we were talking after work. I forgot most of the answers but there's one I still remember. One of the teachers said she really liked watching her boyfriend park his car. She said there is something very sexy about watching a guy look over his shoulder while turning the steering wheel, especially because he uses just one hand to steer. I wonder what the other hand is doing.
back up (computers) - You should always back up your files. If your computer crashes, you may lose all your work.
back off - After their first date, John called Kelly every day, sometimes twice a day. That's just too much. He needs to back off a bit.
