Making a living at it. This is a standard phrase used now in the US. "Surprisingly, the expression can be used with a wide range of prepositions (in, from, by, with, out of) and even no preposition at all." I will take a topic and use all of these prepositions with it, to see what works and is most used here in the US. :) Topic: Truck Driving The below sentences are acceptable and somewhat common, except where noted. 1. If I were a truck driver, I would do my best to make a living with it. 2. I am sure I could make a living from it. 3. I am sure I could make a living at it. (Most commonly used) 4. I am sure I could make a living out of it. 5. I am sure I could make a living in truck driving. (This would be acceptable, but is not used often.) 6. Are you able to make a living with it? 7. If I work hard, I can make a living at it. 8. Can you make a living by driving trucks? (I have never heard: "Can you make a living by it?" ) 9. ( I have rarely, if ever, heard: Can you make a living in it?) Hope this was helpful. :)
