Income. Profit. Proceeds. Revenue. I notice in the course of studying vocabulraies that income,profit,proceeds and revenue, all indicating a certain amount of money from running a business, are quite close in their own meanings and find it ambiguous to discern them from each for actual meaning and use. will be O.K to just grab and hold them in one category assuming these are of one kind, If not How would you separate which from which? Your thoughts, own definition and included examples will be much appreciated.
