The verb create, at its most general, means to bring something into being. To devise something is to plan it or think it up. The main action of devise occurs in the mind. An economist may devise a plan or a strategy, for instance, with the goal of creating jobs or wealth. In some older uses, devise carried nefarious and deceptive undertones, as in "The conspirators devised the downfall of the ruler." Nowadays, devise is more neutral, though it may still have a plot or two up its sleeve.

Isn't it amazing how easy it is to overuse the word amazing? Prodigious is a more specific descriptor. Like amazing, prodigious conveys a sense of wonder, but it is used to comment on the size, amount, extent, or degree of what is being described. Items described as prodigious are extraordinary by one of these measures, as a musician with prodigious talent, a research grant of a prodigious amount, or a career notable for its prodigious output.

To illuminate is to supply with light or to light up. But this verb is not used in exactly the same way as the much more general verb light. For instance, light is more appropriate to talk about the action of igniting or setting something to burn, as a candle. But illuminate is more appropriate for talking about what that lit candle will do: illuminate the room! Stars illuminate the night sky, just as festive lights illuminate residential streets during the holidays. To illuminate a path forward is to shed light on the best course of action—unless of course the path is a literal one from, say, the mailbox to the front door after sunset. In which case, a flashlight should do the trick! Illuminate can also refer to shedding light on a subject, as if to make it more clear or comprehensible.
