Grammar usage guide and real-world examplesUSAGE SUMMARY
The phrase "reason on" is not a commonly used phrase in written English.
"Reason" is typically used as a verb and can be followed by a preposition, such as "reason about" or "reason with." For example, "Let's reason about the best solution to this problem" or "I tried to reason with him but he wouldn't listen." "Reason on" may be used in rare situations, such as in technical or philosophical writing, to mean to think deeply or contemplate about a particular topic or issue. For example, "The author invites readers to reason on the concept of morality in his latest book." In this case, "reason on" implies a deeper level of contemplation than simply "reasoning about" something.
