The term reasonable is a mathematical catch-all which is often used to hide subtle or complex details from the casual reader, while still expressing the important ideas in a line of reasoning. Often used interchangably with nice. These terms must be applied carefully by the mathematician or the resulting exposition may simply express a truism.
