There is a economic term called "return on investment (ROI)."
I wonder if I can only use it a fixed way or if I can use it as a verb "return on" as in the following sentence?
Most of the time, such as large investment schemes can need a substantial amount of money, and it could take years to finish and return on.
or do I have to use "it/them" at the end if I do use "investment" as a subject?
Most of the time, such as large investment schemes can need a substantial amount of money, and it could take years to finish and return on it.
Or should I use another subject all along at best because it is used mostly as noun?
Most of the time, such as large schemes/projects/programs can need a substantial amount of money, and it could take years to finish and realize a return on investment.
